| 1 | Copper-Bismuth Bimetallic Microspheres for Selective Electrocatalytic Reduction of CO2 to Formate显示文摘Summary of main observation and conclusion Electrocatalytic carbon dioxide reduction holds great promise for reducing the atmospheric CO2 level and alleviating the energy crisis. High-performance electrocatalysts are often required in order to lower the high overpotential and expedite the sluggish reaction kinetics of CO2 electroreduction. Copper is a promising candidate metal. However, it usually suffers from the issues of poor stability and low product selectivity. In this work, bimetallic Cu-Bi is obtained by reducing the microspherical copper bismuthate (CuBi2O4) for selectively catalyzing the CO2 reduction to formate (HCOO-). The bimetallic Cu-Bi electrocatalyst exhibits high activity and selectivity with the Faradic efficiency over 90% in a wide potential window. A maximum Faradaic efficiency of ~95% is obtained at -0.93 V versus reversible hydrogen electrode. Furthermore, the catalyst shows high stability over 6 h with Faradaic efficiency of -95%. This study provides an important clue in designing new functional materials for CO2 electroreduction with high activity and selectivity. | Lin Jia Hui Yang Jun Deng Junmei Chen Yuan Zhou Pan Ding Leigang Li Na Han Yanguang Li | 2019 | Chinese Journal of Chemistry2019，37，5： | 8 |
| 2 | Identifying neutral allele Sb at pollen-sterility loci in cultivated rice with Oryza rufipogon origin显示文摘Pollen sterility is commonly found in the intra-specific hybrids of indica and japonica rice,which is one of the main constrains for the utilization of heterosis between indica and japonica.Six loci controlling the pollen sterility of F1 between indica and japonica have been identified from previous studies.Neutral alleles at each locus are potential to overcome the F1 pollen sterility associated with the locus.Therefore,exploitation and utilization of neutral alleles are of significant importance.The present research was based on fine mapping of the F1 pollen-sterility gene Sb and the abundant genetic diversity of Oryza rufipogon Griff.indigenous to Gaozhou,Guangdong Province(referred to as Gaozhou wild rice).Crosses were made using Taichung65(with the genotype of SbjSbj and referred to as E1) and its near-isogenic line of F1 pollen sterility gene Sb(with the genotype of SbiSbi,E2) as female parents,and 12 different accessions of Gaozhou wild rice as male parents.F1 pollen fertility was examined to identify the materials having the neutral alleles at the F1 pollen-sterility locus.Segregation of 4 molecular markers tightly linked with the Sb locus was analyzed in the F2 populations derived from the F1s carrying the neutral gene.The pollen fertility related to the 3 genotypes of the molecular markers was also checked by statistical test to determine whether it was consistent with the hypothesis.The results showed that the pollen fertility of two F1s from one accession of Gaozhou wild rice(GZW099) with E1 and E2 was(89.22±1.07)% and(85.65±1.05)%,respectively.Both of them were fertile and showed no significant difference by t-test.Segregation of the 3 genotypes of the 4 molecular markers followed the expected Mendelian ratio(1:2:1) in the F2 populations.There was no significant difference for the averaged pollen fertility of the plants related to the 3 genotypes,suggesting that no interaction exists between the alleles at the Sb locus in GZW099 and Taichung65 or E2.Evidentially,GZW099 carried the neutral gene(named SbnSbn) at the Sb locus,which provides valuable theoretical basis and resources for further studying and overcoming the sterility of indica-japonica hybrids. | SHI LeiGang LIU XiangDong LIU Bo ZHAO XingJuan WANG Lan LI JinQuan LU YongGen | 2009 | Chinese Science Bulletin2009，54，20： | 5 |
| 3 | Partially hydroxylated ultrathin iridium nanosheets as efficient electrocatalysts for water splitting显示文摘Ultrathin two-dimensional(2D)materials have attracted considerable attention for their unique physicochemical properties and promising applications;however,preparation of freestanding ultrathin 2D noble metal remains a significant challenge.Here,for the first time,we report use of a wet-chemical method to synthesize partially hydroxylated ultrathin Ir nanosheets(ir-NSs)of only five to six atomic layers*thickness.Detailed analysis indicates that the growth confinement effect of carbon monoxide and the partially hydroxylated surface play a critical role in formation of the ultrathin structure.The ultrathin Ir-NSs exhib让excellent performance for both the hydrogen evolution reaction and oxygen evolution reaction in a wide pH range,outperforming the state-of the-art Pt/C and IrO2,respectively.Density-functional theory calculations reveal that the partial hydroxylation not only enhances the surface electron transfer between Ir-sites and intermediate O-species,but also guarantees efficient irdtial activation ofbond cleavage of H-O-H for first-step H2O splitting.This;ultimately,breaks through barriers to full water splitting,with efficient electron transfer essentially maintained. | Zifang Cheng Bolong Huang Yecan Pi Leigang Li Qi Shao Xiaoqing Huang | 2020 | National Science Review2020，7，8： | 4 |

| 5 | Selective electrocatalytic CO2 reduction enabled by SnO2 nanoclusters显示文摘The development of high-performance electrocatalysts holds the decisive key to the electrochemical CO2 reduction toward value-added products. Formic acid or formate is a desirable reduction product, but its selective production is often challenging. Tin based-materials have attracted great attention for formate production, and yet their performances are far from satisfactory. In this study, we reported the preparation of SnO2 nanoclusters from the controlled self-polymerization of dopamine together with SnO32-, followed by the mild-temperature calcination. The final product consisted of large primary particles that were further made of small secondary SnO2 nanocrystals. When evaluated as the electrocatalyst for CO2 reduction in 0.5 M NaHCO3, our material exhibited impressive activity, selectivity and stability for the selective CO2 reduction to formate. A peak formate Faradaic efficiency of^73% and large partial current density of 16.3 mA/cm2 was achieved at -0.92 V versus reversible hydrogen electrode. | Hui Yang Yang Huang Jun Deng Yunling Wu Na Han Chenyang Zha Leigang Li Yanguang Li | 2019 | Journal of Energy Chemistry2019，28，10： | 3 |
| 6 | Reliability analysis based on a novel density estimation method for structures with correlations显示文摘Estimating the Probability Density Function(PDF) of the performance function is a direct way for structural reliability analysis,and the failure probability can be easily obtained by integration in the failure domain.However,efficiently estimating the PDF is still an urgent problem to be solved.The existing fractional moment based maximum entropy has provided a very advanced method for the PDF estimation,whereas the main shortcoming is that it limits the application of the reliability analysis method only to structures with independent inputs.While in fact,structures with correlated inputs always exist in engineering,thus this paper improves the maximum entropy method,and applies the Unscented Transformation(UT) technique to compute the fractional moments of the performance function for structures with correlations,which is a very efficient moment estimation method for models with any inputs.The proposed method can precisely estimate the probability distributions of performance functions for structures with correlations.Besides,the number of function evaluations of the proposed method in reliability analysis,which is determined by UT,is really small.Several examples are employed to illustrate the accuracy and advantages of the proposed method. | Baoyu LI Leigang ZHANG Xuejun ZHU Xiongqing YU Xiaodong MA | 2017 | Chinese Journal of Aeronautics2017，30，3： | 2 |
| 7 | Atomically isolated Pd sites within Pd-S nanocrystals enable trifunctional catalysis for direct,electrocatalytic and photocatalytic syntheses of H_(2)O_(2)显示文摘Although high-efficiency production of hydrogen peroxide(H_(2)O_(2))can be realized separately by means of direct,electrochemical,and photocatalytic synthesis,developing versatile catalysts is particularly challenging yet desirable.Herein,for the first time we reported that palladium-sulphur nanocrystals(Pd-S NCs)can be adopted as robust and universal catalysts,which can realize the efficient O_(2) conversion by three methods.As a result,Pd-S NCs exhibit an excellent selectivity(89.5%)to H_(2)O_(2)with high productivity(133.6 mol·kgcat^(−1)·h^(−1))in the direct synthesis,along with the significantly enhanced H_(2)O_(2)production activity and stability via electrocatalytic and photocatalytic syntheses.It is demonstrated that the isolated Pd sites can enhance the adsorption of O_(2) and inhibit its O–O bond dissociation,improving H_(2)O_(2)selectivity and reducing H_(2)O_(2)degradation.Further study confirms that the difference in surface atom composition and arrangement is the key factor for different ORR mechanisms on Pd NCs and Pd-S NCs. | Tang Yang Chengyong Yang Jiabo Le Zhiyong Yu Lingzheng Bu Leigang Li Shuxing Bai Qi Shao Zhiwei Hu Chih-Wen Pao Jun Cheng Yonggang Feng Xiaoqing Huang | 2022 | Nano Research2022，15，3： | 2 |

| 9 | One-dimensional iridium-based nanowires for efficient water electrooxidation and beyond显示文摘The sluggish reaction kinetics of oxygen evolution reaction(OER)has largely lowered the efficiency of electrochemical water splitting.Ir represents one of the state-of-the-art electrocatalysts for promoting OER especially in acidic electrolytes.However,it remains a formidable challenge to synthesize high-quality one-dimensional(1D)Ir-based nanostructures for improved electrocatalytic performance.Herein,a template-assisted synthesis method is reported wherein 1D porous Ir-Te nanowires(Ir-Te NWs)are synthesized with Te NWs serving as the template.The Ir-Te NWs exhibit highly enhanced OER performance compared to commercial IrO_(2) and Ir/C.In detail,the overpotentials to reach 10 mA cm^(-2) are 248 and 284 mV in 1 M KOH and 0.5 M H2S04,respectively,much lower than those of commercial catalysts.The Ir-Te NWs also show smaller Tafel slopes than commercial IrO_(2) and Ir/C,signifying faster reaction kinetics.Besides,much more durable OER activity can be maintained for Ir-Te NWs with negligible decay during 25 and 20 h stability tests in 1 M KOH and 0.5 M H_(2)SO_(4),respectively.Further analysis indicates that the significantly improved OER performance of Ir-Te NWs could be ascribed to the larger electrochemical surface area and smaller electrical resistance.More significantly,the templated synthesis of Ir-Te NWs can be facilely extended to the fabrication of other metal-Te NWs including Ru-Te,Rh-Te and Pt-Te NWs.The design and synthesis of 1D metal-based NWs in this work provide important inspiration for the synthesis of diversified 1D metallic nanostructures with distinctly enhanced catalytic performance and beyond. | Leigang Li Pengtang Wang Zifang Cheng Qi Shao Xiaoqing Huang | 2022 | Nano Research2022，15，2： | 1 |

| 11 | Enhancement Mechanism of Cerium in 316LN Austenitic Stainless Steel During Creep at 700 ℃显示文摘Effect of cerium(Ce)on creep strength and microstructure of 316LN austenitic stainless steel(316LN steel)at 700℃/150 MPa was investigated by scanning electron microscopy(SEM),scanning transmission electron microscopy(STEM)and thermodynamic calculations.Addition of 0.032 wt%Ce to 316LN steel results in a prominent increase in creep life from 313 to 556 h.Ce enriches in titanium nitride nanoparticles,increases slightly the activity and diffusion coefficient of Mo,and facilitates the formation of fine and dense intragranular Laves phase precipitates.Thus the creep strength is remarkably enhanced by Ce addition in 316LN steel through the intragranular Laves phase precipitation strengthening.It reveals a new insight into the improvement effect of rare earth(RE)elements such as Ce on creep strength of austenitic stainless steels,which inspired the design of RE-microalloying heat-resistant steels. | Renxian Yang Xin Cai Leigang Zheng Xiaoqiang Hu Dianzhong Li | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，3： | 1 |
| 12 | Face-centered cubic structured RuCu hollow urchin-like nanospheres enable remarkable hydrogen evolution catalysis显示文摘Ruthenium(Ru)is one of the most promising metals for its versatility in driving a wide range of catalytic reactions.However,owing to the intrinsic preference of hexagonal close-packed(hcp)phase for bulk Ru,currently,it is still challenging to construct Ru-based nanomaterials with face-centered-cubic(fcc)phase for optimizing their performance towards potential applications.Herein,we report a facile wet-chemical method to directly create unconventional fcc-structured Ru-copper hollow urchin-like nanospheres(fcc-RuCu HUNSs)as a class of efficient pH-universal hydrogen evolution reaction(HER)electrocatalyst.Interestingly,this synthetic strategy can be expanded to prepare other fcc-Ru-based alloy nanomaterials.Significantly,the novel fcc-RuCu HUNSs exhibit superior HER performance with the overpotential of only 25,34,40,and 26 m V to reach the current density of 10 mA cm^(-2)in 0.5 M H_(2)SO_(4),0.05 M H_(2)SO_(4),0.1 M KOH,and 1 M KOH,respectively,much lower than those of hcpRuCu HUNSs and commercial Pt/C.Density functional theory(DFT)calculations further indicate that their excellent pH-universal HER performance results from the optimized adsorption free energy of H and work functions.Our work highlights the importance of phase control to design high-efficiency nanocatalysts for relevant catalytic reactions in energy conversion. | Juntao Zhang Jiabo Le Yuanting Dong Lingzheng Bu Ying Zhang Jun Cheng Leigang Li Xiaoqing Huang | 2022 | Science China Chemistry2022，65，1： | 1 |

| 15 | Photon-counting distributed free-space spectroscopy显示文摘Spectroscopy is a well-established nonintrusive tool that has played an important role in identifying and quantifying substances,from quantum descriptions to chemical and biomedical diagnostics.Challenges exist in accurate spectrum analysis in free space,which hinders us from understanding the composition of multiple gases and the chemical processes in the atmosphere.A photon-counting distributed free-space spectroscopy is proposed and demonstrated using lidar technique,incorporating a comb-referenced frequency-scanning laser and a superconducting nanowire single-photon detector.It is suitable for remote spectrum analysis with a range resolution over a wide band.As an example,a continuous field experiment is carried out over 72 h to obtain the spectra of carbon dioxide(CO_(2))and semi-heavy water(HDO,isotopic water vapor)in 6 km,with a range resolution of 60 m and a time resolution of 10 min.Compared to the methods that obtain only column-integrated spectra over kilometer-scale,the range resolution is improved by 2-3 orders of magnitude in this work.The CO_(2)and HDO concentrations are retrieved from the spectra acquired with uncertainties as low as±1.2%and±14.3%,respectively.This method holds much promise for increasing knowledge of atmospheric environment and chemistry researches,especially in terms of the evolution of complex molecular spectra in open areas. | Saifen Yu Zhen Zhang Haiyun Xia Xiankang Dou Tengfei Wu Yihua Hu Manyi Li Mingjia Shangguan Tianwen Wei Lijie Zhao Lu Wang Pu Jiang Chengjun Zhang Lixing You Leigang Tao Jiawei Qiu | 2021 | Light(Science & Applications)2021，10，11： | 1 |
| 16 | Modulate the electronic structure of Cu_(7)S_(4)nanosheet on TiO_(2)for enhanced photocatalytic hydrogen evolution显示文摘TiO_(2)is a promising photocatalyst due to its high thermodynamic stability and non-toxicity.However,its applications have been still limited because of the high recombination rate of electron-hole pairs.Herein,we show that by combining heterojunction construction and electronic structure regulation,the electron-hole pairs in TiO_(2)can be effectively separated for enhanced photocatalytic hydrogen evolution.The optimized Cu_(7)S_(4)nanosheet decorated TiO_(2)achieves much enhanced H_(2)evolution rate(11.5 mmol·g−1·h−1),which is 13.8 and 4.2 times of that of TiO_(2)and Cu_(7)S_(4)/TiO_(2),respectively.The results of photoluminescence spectroscopy,transient photocurrent spectra,ultraviolet-visible diffuse reflectance spectra,and electrochemical impedance spectroscopy collectively demonstrate that the enhanced photocatalytic performance of Air-Cu_(7)S_(4)/TiO_(2)is attributed to the effective separation of charge carriers and widened photoresponse range.The electron paramagnetic resonance and X-ray photoelectron spectroscopy results indicate that the increase of Cu2+in the Cu_(7)S_(4)nanosheet after calcination can promote the charge transfer.This work provides an effective method to improve the electron migration rate and charge separation of TiO_(2),which holds great significance for being extended to other material systems and beyond. | Wenqiang Liu Huiping Peng Leigang Li Mingmin Wang Hongbo Geng Xiaoqing Huang | 2023 | Nano Research2023，16，4： | 0 |
| 17 | Phase and structure modulating of bimetallic Cu/In nanoparticles realizes efficient electrosynthesis of syngas with wide CO/H_(2) ratios显示文摘Syngas(CO+H_(2))is the incredibly important feedstock for producing synthetic fuels and various value-added chemicals.CO_(2) electrochemical reduction to syngas is an environmental-friendly and sustainable approach,but still challenging to produce tunable syngas with a wide ratio of CO+H_(2).Herein,by modulating the structure and phase,we have successfully obtained a series of copper-indium(Cu-ln)catalysts,which are efficient for producing syngas with tunable CO+H_(2) ratios.A series of Culn bimetallic catalysts with different structures from hollow sphere to two-layer hollow sphere and different phases from CuO to CU_(2)O are developed.We find that the CO and H2 are the only gaseous products,in which the CCD/H_(2) ratios can be readily tuned from 1.2±0.1 to 9.0±1.5 by simply controlling the thermal annealing temperature.It also exhibits high durability during a 10-h test.The unique performance is attributed to the modulated In enrichment on the Cu surfaces during the CO_(2) reduction reaction,which causes the differences in binding energies for key reaction intermediates,thus resulting in the tunable composition of syngas.The present work emphasizes a simple yet efficient phase and structure modulating strategy for designing potential electrocatalysts for producing syngas with widely tunable CO+H_(2) ratios. | Chenqi Shen Pengtang Wang Leigang Li Xiaoqing Huang Qi Shao | 2022 | Nano Research2022，15，1： | 0 |
| 18 | Novel vertically aligned nanocomposite of Bi_(2)WO_(6)-Co_(3)O_(4) with room-temperature multiferroic and anisotropic optical response显示文摘A new vertically aligned nanocomposite(VAN)structure based on two-dimensional(2D)layered oxides has been designed and self-assembled on both LaAlO_(3)(001)and SrTiO3(001)substrates.The new VAN structure consists of epitaxially grown Co_(3)O_(4) nanopillars embedded in the Bi_(2)WO_(6) matrix with a unique 2D layered structure,as evidenced by the microstructural analysis.Physical property measurements show that the new Bi_(2)WO_(6)-Co_(3)O_(4) VAN structure exhibits strong ferromagnetic and piezoelectric response at room temperature as well as anisotropic permittivity response.This work demonstrates a new approach in processing multifunctional VANs structure based on the layered oxide systems towards future nonlinear optics,ferromagnets,and multiferroics. | Leigang Li Shikhar Misra Xingyao Gao Juncheng Liu Han Wang Jijie Huang Bruce Zhang Ping Lu Haiyan Wang | 2021 | Nano Research2021，14，12： | 0 |
| 19 | Study of the Judder Characteristics of Friction Material for an Automobile Clutch and Test Verification显示文摘The friction judder characteristics during clutch engagement have a significant influence on the NVH of a driveline.In this research,the judder characteristics of automobile clutch friction materials and experimental verification are studied.First,considering the stick-slip phenomenon in the clutch engagement process,a detailed 9-degrees-of-freedom(DOF)model including the body,each cylinder of the engine,clutch and friction lining,torsional damper,transmission and other driveline parts is established,and the calculation formula of friction torque in the clutch engagement process is determined.Second,the influence of the friction gradient characteristics on the amplification or attenuation of the automobile friction judder is analyzed,and the corresponding stability analysis and the numerical simulation of different friction gradient values are carried out with MATLAB/Simulink software.Finally,judder bench test equipment and a corresponding damping test program are developed,and the relationship between the friction coefficient gradient characteristics and the system damping is analyzed.After a large number of tests,the evaluation basis of the test is determined.The research results show that the friction lining with negative gradient characteristics of the friction coefficient will have a judder signal.When the friction gradient value is less than-0.005 s/m,the judder signal of the measured clutch cannot be completely attenuated,and the judder phenomenon occurs.When the friction gradient is greater than-0.005 s/m,the judder signal can be significantly suppressed and the system connection tends to be stable. | Zhengfeng Yan Hangsheng Li Hairui Lei Maoqing Xie Leigang Wang | 2023 | Chinese Journal of Mechanical Engineering2023，36，2： | 0 |
| 20 | Redistribution of C and N Atoms in High Nitrogen Martensitic Stainless Steel During Cryogenic Treatment显示文摘The redistribution of C and N atoms during cryogenic treatment is crucial for the microstructure evolution and properties of high nitrogen martensitic steel.Here,the distinct redistribution behavior of C and N atoms in a martensitic stainless steel with 0.3 wt%C and 0.5 wt%N after cryogenic treatment were investigated by the atom probe tomography.Carbon clusters begin to form after cryogenic treatment at-60℃and gradually increase with the decrease of cryogenic treatment temperature.While Mo–N and Cr–N pairs are homogeneously distributed in the matrix even after cryogenic treatment at-120℃,and then form enrichment phenomenon when the cryogenic temperature is deeply lowered to-190℃.It is found that the distinct redistributions of C and N atoms are associated with the different interaction energy between substitutional atoms and them.The stronger interaction between Cr,Mo atoms and N delays the segregation of N during the cryogenic treatment.Finally,the mechanical properties results confirmed that the deep lower cryogenic treatment is a promising method to improve the hardness and strength in the high nitrogen martensitic stainless steel. | Xin Cai Xiaoqiang Hu Leigang Zheng Dianzhong Li | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，4： | 0 |
