| 1 | Adaptive and regulatory mechanisms in aged rats with postoperative cognitive dysfunction显示文摘Inflammation may play a role in postoperative cognitive dysfunction. 5′ Adenosine monophosphate-activated protein kinase, nuclear factor-kappa B, interleukin-1β, and tumor necrosis factor-α are involved in inflammation. Therefore, these inflammatory mediators may be involved in postoperative cognitive dysfunction. Western immunoblot analysis revealed 5′ adenosine monophosphate-activated protein kinase and nuclear factor-kappa B in the hippocampus of aged rats were increased 1–7 days after splenectomy. Moreover, interleukin-1β and tumor necrosis factor-α were upregulated and gradually decreased. Therefore, these inflammatory mediators may participate in the splenectomy model of postoperative cognitive dysfunction in aged rats. | Yanlin Bi Shuyun Liu Xinjuan Yu Mingshan Wang Yuelan Wang | 2014 | Neural Regeneration Research2014，9，5： | 17 |
| 2 | Waste heat recovery from heavy-duty diesel engine exhaust gases by medium temperature ORC system显示文摘A medium-temperature waste-heat recovery system based on the organic Rankine cycle (ORC) is designed to recover the exhaust energy from a heavy-duty diesel engine. Analysis of the 1st law of thermodynamics for an ORC system is performed. This analysis contains two parts. The first part is an analysis with undefined heat exchangers to gain an understanding of the ORC and find out suitable organic fluid parameters for a better ORC efficiency. The second part of the analysis uses combined engine test results and two designs of heat exchangers. By comparing the two designs, an improved system of heat exchangers is described. This analysis also quantifies the effect of engine parameters on ORC system. The study concludes that the supercritical Rankine cycle is a better approach towards waste heat recovery. The ORC system is found to perform better under part-load conditions if the medium-high power condition rather than rated working point of the engine is used as the design parameter. The ORC system achieves the highest waste-heat recovery efficiency of up to 10-15% for the optimised heat ex-changer design. | WEI MingShan FANG JinLi MA ChaoChen DANISH Syed Noman | 2011 | Science China(Technological Sciences)2011，54，10： | 16 |
| 3 | Acupuncture preconditioning protects hippocampal neurons from transient ischemia/reperfusion injury显示文摘The present study established a model of brain ischemia in aged rats using four-vessel occlusion.We observed hippocampal CA1 neuronal apoptosis and apoptosis-mediated protease caspase-3 expression following preconditioning of electroacupuncture at Baihui(GV 20).Our results showed that the number of hippocampal CA1 normal neurons was decreased,and degenerated neurons were increased 12 hours to 3 days following cerebral ischemia/reperfusion.The number of hippocampal CA1 apoptotic neurons and caspase-3-positive neurons in rats with cerebral ischemia/reperfusion injury was significantly decreased following acupuncture preconditioning.Acupuncture preconditioning protects aged rats against ischemia/reperfusion injury by regulating caspase-3 protein expression. | Mingshan Wang Haipeng Zhou Fei Shi Shilong Ma Yanlin Bi Yuqiu Liu Hong Liu Haiou Li | 2011 | Neural Regeneration Research2011，6，15： | 12 |
| 4 | Visible-light-driven Ag/Ag_3PO_4-based plasmonic photocatalysts:Enhanced photocatalytic performance by hybridization with graphene oxide显示文摘An efficient visible-light-driven plasmonic photocatalyst with regard to graphene oxide(GO) hybridized Ag/Ag3PO4(Ag/Ag3PO4/GO) nanostructures has been facilely synthesized via a deposition-precipitation method.The synthesized nanostructures have been characterized by means of scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy(EDX),X-ray diffraction(XRD),UV-vis spectra,Fourier transform infrared spectra(FT-IR),X-ray photoelectron spectroscopy(XPS),and Raman spectra.It has been disclosed that compared with the bare Ag/Ag3PO4 nanospecies,the GO hybridized nanostructures display enhanced photocatalytic activity for the photodegradation of methyl orange pollutant under visible-light irradiation.It is suggested that the reinforced charge transfer and the suppressed recombination of electron-hole pairs in Ag/Ag3PO4 /GO,the smaller size of Ag/Ag3PO4 nanospecies in Ag/Ag3PO4/GO,all of which are the consequences of the hybridization of GO,are responsible for the enhanced photocatalytic performance.The investigation might open up new opportunities to obtain highly efficient Ag3PO4-based visible-light-driven plasmonic photocatalyst for the photodegradation of organic pollutants. | ZHU MingShan CHEN PengLei LIU MingHua | 2013 | Chinese Science Bulletin2013，58，1： | 10 |

| 6 | 2D Bi2WO6/MoS2 as a new photo-activated carrier for boosting electrocatalytic methanol oxidation with visible light illumination显示文摘In this paper,a new two-dimensional(2 D)/2 D composite of Bi2 WO6/MoS2 was facile synthesized,and then was used as supporting material for depositing Pt nanoparticles.The as-synthesized Pt-Bi2 WO6/MoS2 was extended into photo-assisted electrocatalytic oxidation of methanol,which is a model anode reaction for direct methanol fuel cell.Compare with traditional electrocatalytic process,PtBi2 WO6/MoS2 displays 1.5 times enhanced electrocatalytic performance on methanol oxidation with assistance of visible light irradiation and 2.2 times for commercial Pt/C.Besides,from the results of chronoamperometric and chronopotentiometry experiments,the stability of Pt-Bi2 WO6/MoS2 electrode is clearly improved under visible light irradiation.The synergistic effects of photo-and electro-catalytic in the heterojunction of Pt-Bi2 WO6/MoS2 in favor of the above enhancement.This research gives more insights in the fields of photo-assisted traditional electrocatalytic application by constructing of semiconductor heterojunction carrier. | Hongmin Zhang Jie He Chunyang Zhai Mingshan Zhu | 2019 | Chinese Chemical Letters2019，30，12： | 5 |

In this paper, the authors analyze the annual rate of carbon productivity growth, the differences of carbon productivity of different countries, and the factors for enhancing carbon productivity. Consequently, the authors clarify their viewpoint that the annual rate of carbon productivity growth can be used to weigh the efforts that a country takes to address climate change, and propose policies and suggestions on promoting carbon production. | He Jiankun Su Mingshan | 2011 | Chinese Journal of Population,Resources and Environment2011，9，1： | 5 |
| 8 | Identifying changes in the wheat kernel proteome under heat stress using iTRAQ显示文摘Wheat(Triticum aestivum L.) is one of the three major global food crops. Hightemperature stress can affect its yield and quality. Studies of the effect of hightemperature stress on wheat kernel development are important because they can reveal the stability of wheat quality and lead to the genetic improvement of wheat quality traits. In this study, the isobaric tags for relative and absolute quantitation(iTRAQ)method was adopted to analyze changes in the protein expression profile of wheat cultivars under high temperature stress. The protein content of wheat grain increased under heat stress, while the SDS-sedimentation value and starch content decreased.Grain filling was deficient under high temperature stress, which reduced thousandkernel weight but did not affect wheat kernel length. The 207 differentially expressed proteins identified in Gaocheng 8901 under heat stress were associated with energy metabolism, growth and development, and stress response. Gene Ontology enrichment analysis showed that the annotated proteins that were differentially expressed in Gaocheng 8901 under heat stress were involved mainly in stimulus response, abiotic stress response, stress response, and plasma membrane. A set of 78 differentially expressed proteins were assigned to 83 KEGG signaling/metabolic pathways. KEGG pathway enrichment analysis showed that this set of proteins was significantly enriched in members of 51 pathways, and the proteins participated mainly in protein synthesis in the endoplasmic reticulum, starch and sucrose metabolism, and reaction on ribosomes. Five differentially expressed proteins were involved in protein–protein interaction networks that may greatly influence the yield and quality of wheat grain. In wheat, high-temperature stress leads to a variety of effects on protein expression and may ultimately cause changes in yield and quality. | Yufeng Zhang Hongyao Lou Dandan Guo Ruiqi Zhang Meng Su Zhenghong Hou Haiying Zhou Rongqi Liang Chaojie Xie Mingshan You Baoyun Li | 2018 | The Crop Journal2018，6，6： | 5 |
| 9 | Construction of piezoelectric BaTiO_(3)/MoS_(2) heterojunction for boosting piezo-activation of peroxymonosulfate显示文摘The rapid recombination of charge carriers in piezoelectric materials has always been the problem that limits their piezoelectric performance for removal of organic pollutants in water.Herein,we construct a piezoelectric Ba TiO_(3)/MoS_(2)(BTO/MS)that follows a type II heterojunction charge transfer system to inhibit the recombination of electron-hole(e^(-)-h^(+))pairs,which is beneficial to the activation of peroxymonosulfate(PMS)for the removal of antibiotic ornidazole(ORZ)pollutants.The optimal ratio of BTO/MS for ORZ degradation under the piezo/PMS process is 13.9,3.6,62.1 and 2.0 times higher than that of the BTO/piezo,MS/piezo,(BTO/MS)/PMS and(BTO/MS)/piezo processes,respectively.The high efficiency charge separation in the piezoelectric heterojunction of BTO/MS promotes the activation of PMS,resulting in the synergy of pizeocatalysis and PMS oxidation during the process of ORZ degradation.This study provides an idea for enhancing piezo-activation of PMS by constructing heterojunctions in piezoelectric materials. | Yanxi Chen Shenyu Lan Mingshan Zhu | 2021 | Chinese Chemical Letters2021，32，6： | 5 |
| 10 | Effects of Huatan Tongluo decoction on vascular endothelial growth factor receptor 2 expression in synovial tissues of rats with collagen-induced arthritis显示文摘OBJECTIVE: To determine the therapeutic effect and potential mechanism of Huatan Tongluo decoction on rats with collagen-induced arthritis.METHODS: Forty specific pathogen-free Wistar rats were selected, and 10 were randomly selected as the control(group 1). The remaining rats were injected intradermally with emulsified type Ⅱ bovine collagen at the tail base and back, followed by a booster 7 d post first immunization. After establishing collagen-induced arthritis(CIA), rats were randomly divided into three groups(n = 10). The rats were treated orally for 30 d as follows: group 1, saline; group 2, model(saline); group 3, tripterygium polyglycoside(TP; 7.81 mg/kg, positive control);group 4, Huatan Tongluo decoction(HTTL; 7.5 g/kg). Body weight, ankle swelling and arthritis index were measured over the course of the study. The rats were sacrificed 30 d after treatment. Morphological changes in the synovium were observed by hematoxylin and eosin staining. Pannus formation and synovial thickness in the left ankle were observed by color Doppler ultrasoundVascular endothelial growth factor(VEGF) and VEGFR2 protein levels were measured by immunohistochemistry.VEGF/VEGFR2 mRNA levels were measured by real-time quantitative polymerase chain reaction.RESULTS: Compared with the model group, a significantly lower arthritis index was observed in the positive control group(P < 0.05) and HTTL group(P < 0.01), after treatment. Both positive control and HTTL reduced intra-articular pannus formation and synovial thickening. Furthermore, VEGF mRNA,and VEGFR2 protein and mRNA levels were significantly downregulated(P < 0.05) in the treatment groups.CONCLUSION: Inhibition of the expression of VEGF and VEGFR2 in synovial tissues and the formation of pannus and synovial hyperplasia may be part of the mechanism of HTTL for relieving the symptoms of rheumatoid arthritis in CIA rats. | Chen Jinchun Qiu Mingshan Li Yihan Zhang Qian Zhang Yiyan Lin Shuangjie Zhang Shaohong Qian Lixia Gao Hai Li Liang-cheng | 2019 | Journal of Traditional Chinese Medicine2019，39，2： | 4 |
| 11 | Protective effects of acupuncture on brain tissue following ischemia/reperfusion injury显示文摘BACKGROUND: In patients with cerebrovascular disease, by means of the neuroendocrine system, acupuncture supports the transformation of a local pathological status into a physiological status. Recently, great progress has been made in studying the protective effects of acupuncture on brain ischemia/reperfusion injury. OBJECTIVE: To summarize research advances in the protective effects of acupuncture on brain ischemia/reperfusion injury. RETRIEVAL STRATEGY: Using the terms 'acupuncture, transcutaneous electrical acupoint stimulation, cerebral ischemia/reperfusion injury, and cerebral protection', we retrieved articles from the PubMed database published between January 1991 and June 1994. Meanwhile, we searched the China National Knowledge Infrastructure with the same terms. Altogether, 114 articles and their results were analyzed. Inclusive criteria: studies that were closely related to the protective effects of acupuncture on brain ischemia/reperfusion injury, or studies, whose contents were in the same study field and were published recently, or in the authorized journals. Exclusive criteria: repetitive studies. LITERATURE EVALUATION: Thirty articles that related to the protective effects of acupuncture on brain ischemia/reperfusion injury were included. Among them, 7 were clinical studies, and the remaining 23 articles were animal experimental studies. DATA SYNTHESIS: ① Animal experimental studies have demonstrated that acupuncture improves brain blood perfusion and brain electrical activity, influences pathomorphological and ultramicrostructural changes in ischemic brain tissue, is beneficial in maintaining the stability of intracellular and extracellular ions, resists free radical injury and lipid peroxidation, and influences cytokine, neurotransmitter, brain cell signal transduction, and apoptosis-regulating genes. ② Clinical studies have demonstrated that acupuncture not only promotes nutritional supply to local brain tissue in patients with cerebral infarction, but also increases brain blood flow and attenuates inflammatory reactions of injured brain tissue. ③ At present, the mechanisms underlying the protective effects of acupuncture on brain ischemia/reperfusion injury have been greatly studied. Some conclusions, however, are not sufficient or comprehensive, and remain as primarily isolated incidents. CONCLUSION: Studies that focused on mechanisms that influence the protective effects of acupuncture on brain ischemia/reperfusion injury have provided results; however, several mechanisms are still poorly understood. The goals for studying the mechanistic actions of acupuncture are to not only investigate the various protective effects of acupuncture on ischemic brain injury, but to also understand the internal associations between the various protective effects and their common mechanistic actions. | Mingshan Wang Fuguo Ma Huailong Chen | 2008 | Neural Regeneration Research2008，3，3： | 4 |

| 13 | Edema and neuronal apoptosis in the hippocampus and cortex of elderly rats following transient cerebral ischemia/reperfusion injury显示文摘BACKGROUND: Previous studies of cerebral ischemia have used young animals, with an ischemictime greater than 5 minutes (safe time limit). Despite an increased understanding of neuronalapoptosis, it remains uncertain whether brief cerebral ischemic events of 5 minutes or less damagebrain tissue in elderly rodents.OBJECTIVE: To investigate the effects of transient cerebral ischemia (5 minutes)/reperfusion injuryon brain cortical and hippocampal edema, aquaporin-4 (AQP-4) expression, and neuronal apoptosisin aged rats, and to compare ischemic sensitivity between cortex and hippocampus.DESIGN, TIME AND SETTING: A randomized, controlled, animal experiment was performed at theInstitute of Cerebrovascular Disease, Qingdao University Medical School from April 2008 to March2009.MATERIALS: Rabbit anti-AQP-4 polyclonal antibody, TUNEL kit, and SABC immunohistochemistrykit were purchased from Wuhan Boster Bioengineering, China.METHODS: A total of 160 healthy, male, aged 19-21 months, Wistar rats were randomly assignedto 4 groups: sham-surgery, and ischemia 1-, 3-, and 5-minute groups, with 40 rats in each group.The global cerebral ischemia model was established using the Pusinelli four-vessel occlusion, andthe three cerebral ischemia groups were subdivided into reperfusion 12-hour, 1-, 2-, 3-, and 7-daysubgroups, with 8 rats in each subgroup. The sham-surgery group was subjected to exposure of thefirst cervical bilateral alar foramina and bilateral common carotid arteries.MAIN OUTCOME MEASURES: The dry-wet weight assay was used to measure brain water contentand histopathology of the cortex and hippocampus was observed following hematoxylin-eosinstaining. In addition, cortical and hippocampal AQP-4 expression was detected by streptavidin-biotincomplex immunohistochemistry, and neuronal apoptosis was detected by the TUNEL method.RESULTS: There was no significant difference in brain water content or AQP-4 expression in thecortex and hippocampus between ischemia 1- and 3-minute groups and the sham-surgery group orbrain water content or AQP-4 expression in the cortex between ischemia 5-minute group andsham-surgery group (P> 0.05). However, brain water content and AQP-4 expression in thehippocampus after 5 minutes of cerebral ischemia were significantly increased compared with thesham-surgery group (P < 0.05 or P < 0.01 ). Several TUNEL-positive cells were observed in thecortex and hippocampus of the sham-surgery group and ischemia 1-minute group, as well as in thecortex of the ischemia 3-minute group. In addition, the number of apoptotic neurons in thehippocampus of ischemia 3-minute group and in the cortex and hippocampus of ischemia 5-minutegroup was significantly increased (P < 0.05 or P < 0.01). Neuronal apoptosis was increased after 12hours of ischemia/reperfusion, and it reached a peak by 2 days (P < 0.01).CONCLUSION: Transient cerebral ischemia (5 minutes) resulted in increased hippocampal edema,AQP-4 expression, and neuronal apoptosis. Moreover, cerebral ischemia had a greater effect onneuronal apoptosis than brain edema or AQP-4 expression, and the hippocampus was moresensitive than the cortex. | Mingshan Wang Lina Zhang Xiangyu Ji Yanwei Yin Hui Xu Hong Liu Nianguo Hou | 2009 | Neural Regeneration Research2009，4，12： | 4 |
| 14 | Flow characteristics of tangential leakage in a scroll compressor for automobile heat pump with CO_(2)显示文摘Tangential leakage loss reduction has great significance on improving the performance of scroll compressors.In this study,the flow field of a scroll compressor working with CO_(2) was numerically investigated.The development characteristics of the tangential leakage flow in different working chambers were carried out,which was obtained by analyzing the field quantities distributions.The impacts of the radial clearances and sidewall roughness on the tangential leakage were also taken into consideration,in order to explore the feasible method of the flow control for the tangential leakage in scroll compressors.Results showed that the tangential leakage flow had various characteristics in the suction and compression chambers due to the different interactions between the tangential leakage flow and mainstream.Owing to little reverse pressure gradient,the tangential leakage flow maintained the typical jet form in the suction chambers.By contrast,the mixing of the tangential leakage flow and mainstream induced the passage vortex and secondary flows in the compression chamber.The secondary flow was the primary factor that results in the occurrence of localized high temperature region rather than the tangential leakage.With the increase of the radial clearance,the volumetric efficiency declined and the discharge temperature increased rapidly.In terms of flow control of the tangential leakage,the increase of sidewall roughness by 2μm could achieve the same effect as the decrease of the radial clearance by 4μm,while the volumetric efficiency increased by almost 5%and average discharge temperature decreased by 5K. | ZHENG SiYu WEI MingShan HU ChenXing SONG PanPan TIAN Ran | 2021 | Science China(Technological Sciences)2021，64，5： | 4 |
| 15 | Experimental study of a micro-scale solar organic Rankine cycle system based on compound cylindrical Fresnel lens solar concentrator显示文摘In the present study, a micro-scale solar organic Rankine cycle power generation system was developed. The system comprises of a solar collection system based on compound cylindrical Fresnel lens concentrator and an organic Rankine cycle power generation system integrated with a scroll expander. YD320 and R245 fa were used as the heat transfer fluid and the working fluid, respectively. The effects of the evaporation pressure, the degree of superheat, and the mass flow rate of the working fluid were analyzed to evaluate the solar collection efficiency, the electric power output, the thermal efficiency and exergy efficiency of the system. The results illustrate that both the increasing evaporation pressure and decreasing superheat degree have positive impacts on solar collection efficiency. The electric power increases as the evaporation pressure increases, while the thermal efficiency and the exergy efficiency decrease. However, the system overall efficiency decreases slowly due to the increase of solar collection efficiency. The electric power increases with the increment of the working fluid mass flow rate. The increasing mass flow rate has no visible impact on the thermal and exergy efficiencies of organic Rankine cycle subsystem, whereas a slightly increase of the thermal and exergy efficiencies of the integrated system. The electric power decreases with the increase of the superheat degree, whereas the thermal and the exergy efficiencies of the system increase. The system works more suitably with a higher degree of superheat for the small mass flow rate condition. | MENG Jia SONG PanPan WEI MingShan TIAN GuoHong ZHAO Meng ZHENG HongFei HU GuangDa | 2019 | Science China(Technological Sciences)2019，62，12： | 3 |
| 16 | Preparation of Fe_x Ce_(1-x) O_y solid solution and its application in Pd-only three-way catalysts显示文摘FeO x-CeO 2 mixed oxides with increasing Fe/(Ce+Fe) atomic ratio(1-20 mol%) were prepared by sol-gel method and characterized by X-ray powder diffraction(XRD),Brunauer-Emmett-Teller(BET) and Hydrogen temperature-programmed reduction(H 2-TPR) techniques.The dynamic oxygen storage capacity(DOSC) was investigated by mass spectrometry with CO/O 2 transient pulses.The powder XRD data following Rietveld refinement revealed that the solubility limit of iron oxides in the CeO 2 was 5 mol% based on Fe/(Ce+Fe).The lattice parameters experienced a decrease followed by an increase due to the influence of the maximum solubility limit of iron oxides in the CeO 2.TPR analysis revealed that Fe introduction into ceria strongly modified the textual and structural properties,which influenced the oxygen handling properties.DOSC results revealed that Ce-based materials containing Fe oxides with multiple valences contribute to the majority of DOSC.The kinetic analysis indicated that the calculated apparent kinetic parameters obey the compensation effect.The three-way catalytic performance for Pd-only catalysts based on the Fe doping support exhibited the redundant iron species separated out of the CeO 2 and interacted with the ceria and Pd species on the surface,which seriously influenced the catalytic properties,especially after hydrothermal aging treatment. | Jianqiang Wang Meiqing Shen Jun Wang Mingshan Cui Jidong Gao Jie Ma Shuangxi Liu | 2012 | Journal of Environmental Sciences2012，24，4： | 3 |
| 17 | Two-dimensional TiO_(2)(001)nanosheets as an effective photo-assisted recyclable sensor for the electrochemical detection of bisphenol A显示文摘Electrochemical detection is an efficient method for the detection of Bisphenol A(BPA).Herein,a sensitive photo-electrochemical sensor based on two-dimensional(2 D)TiO_(2)(001)nanosheets was fabricated and then used for BPA electrochemical detection.Upon light irradiation,the 2 D TiO_(2)(001)nanosheets electrode provided a lower detection limit of BPA detection compared with an ambient electrochemical determination.The low detection limit is^5.37 nmol/L(S/N=3).Furthermore,profiting from the photoelectric characteristics,the 2 D TiO_(2)(001)nanosheets electrode exhibits a nice regeneration prope rty.After 45 min of light irradiation,the electrochemical signal was regenerated from14.7%to 82.9%of the original signal at the 6th cycle.This is attributed to the non-selective·OH mediation produced by the 2 D TiO_(2)(001)nanosheets mineralizing anodic polymeric products and resuming surface reactive sites.This investigation indicates that photo-assistance is an efficient method to improve the electrochemical sensor for detecting BPA in water environments. | Sujuan Hu Yingjian Yu Yu Guan Yanhuan Li Baoling Wang Mingshan Zhu | 2020 | Chinese Chemical Letters2020，31，10： | 3 |
| 18 | Palladium-Catalyzed Tandem Carbonylative Aza-Wacker-Type Cyclization of Nucleophile Tethered Alkene to Access Fused N-Heterocycles显示文摘Although tandem reactions offer rapid access to structurally complex molecules in one-pot reaction,the selectivity issue needs to be addressed particularly when incompatible step reactions are involved.Herein,we report the selective synthesis of fused N-heterocycles from nucleophile-tethered alkenylamide and carbon monoxide via palladium(Pd)-catalyzed tandem carbonylative aza-Wacker-type cyclization.The electron-deficient nature of amide N—H and the intramolecular coordination of Pd with alkene accelerate the aminopalladation and effectively prevent the side oxidative carbonylation of diamine moiety to form urea.It is also found that the reported acyl Pd chloride intermediate may not be involved in this tandem cyclization.This work not only provides an efficient synthetic route to fused 1,4-diazepanones and 1,4-diazepanes but also inspires further development of tandem reactions for the diverse synthesis of heterocycles. | Lijun Shi Mingshan Wen Fuwei Li | 2021 | Chinese Journal of Chemistry2021，39，2： | 2 |
| 19 | Efficient ozone decomposition over bifunctional Co_(3)Mn-layered double hydroxide with strong electronic interaction显示文摘Ground-level ozone is one of the primary pollutants detrimental to human health and ecosystems.Catalytic ozone decomposition still suffers from low efficiency and unsatisfactory stability.In this work,we report a manganese-based layered double hydroxide catalyst(Co_(3)Mn-LDH),which exhibited a superior ozone decomposition performance with the efficiency of 100% and stability over 7 h under a GHSV of 2,000,000 mL g^(-1)h^(-1) and relative humidity of 15%.Even when the relative humidity increased to 50%,the ozone decomposition also reached 86%,which significantly exceeds as-synthesized MnO_(2) and commercial MnO_(2) in performance.The catalytic mechanism was studied by H_(2)-TPR,FT-IR and XPS.The excellent performance of Co_(3)Mn-LDH can be attributed to its abundant surface hydroxyl groups that ensured the preferentially surface enrichment of ozone,as well as the cyclic dynamic replenishment of electrons between multivalent Co^(2+)/Co^(3+),Mn^(2+)/Mn^(3+)/Mn^(4+)and oxygen species that endowed the stable ozone decomposition.This work offers new insights into the design of efficient catalysts for ozone pollution control. | Bin Liu Minxian Zhang Jingling Yang Mingshan Zhu | 2022 | Chinese Chemical Letters2022，33，10： | 2 |
