| 1 | Highly stable lead-free Cs3Bi2I9 perovskite nanoplates for photodetection applications显示文摘Lead halide perovskites have received tremendous attentions recently for their excellent properties such as high light absorption coefficient and long charge carrier diffusion length. However, the stability issues and the existence of toxic lead cations have largely limited their applications in optoelectronic area. Herein, we report the synthesis and investigation of highly stable and lead-free Cs3Bi2I9 perovskite nanoplates for visible light photodetection applications. The Cs3Bi2I9 nanoplates were synthesized through a facile solution-processed method, which is also applicable to various substrates. The achieved nanoplates present very good crystal quality and exhibit excellent long-term stability even exposed in moist air for several months. Photodetectors were constructed based on these high-quality perovskite nanoplates for the first time, and display a maximum photoresponsivity of 33.1 mA/W under the illumination of 450 nm laser, which is six times higher than the solution-synthesized CH3NH3PbI3 nanowire photodetectors. The specific detectivity of these devices can reach up to 10^10 Jones. Additionally, the devices exhibit fast rise and decay time of 10.2 and 37.2 ms, respectively, and highly stable photoswitching behavior with their photoresponse well retaining under alternating light and darkness. This work opens up a new opportunity for stable and low-toxic perovskite-based optoelectronic applications. | Zhaoyang Qi Xianwei Fu Tiefeng Yang Dong Li Peng Fan Honglai Li Feng Jiang Lihui Li Ziyu Luo Xiujuan Zhuang Anlian Pan | 2019 | Nano Research2019，12，8： | 7 |
| 2 | Vapor growth of WSe2/WS2 heterostructures with stacking dependent optical properties显示文摘Two-dimensional(2D)vertically stacked heterostructures based on layered transition-metal dichalcogenides(MDCs)have remarkablepote ntial in future applications due to their rich in terlayer related properties,such as in terlayer excitons,tun able interlayer band alignments.However,the controlled growth of TMDC bilayer heterostructures with preferred stacking structure remains challenging.Here,we report atwo-step van der Waals epitaxial vapor growth of WSe2/WS2 vertically stacked bilayer heterostructures with controllable commensurate crystallographic alignments(so called AA and AB stacki ng),by controlling the deposition temperature.Moire patter ns were obtai ned in bothAA and AB stacked WSe2/WS2 heterostructures.The stacking configuration of the vertical heterostructures was verified by the secondharmonic generation signals.Photoluminescenee and Raman spectroscopy studies further confirm that the heterostructures with differentstacking configuration have obviously different optical properties,which is ascribed to the distinct in terlayer coupling and resonance excitation between the distinguishing AA and AB stacked heterostructures.The controlled growth of AA and AB stacked heterostructures could provide an importa nee platform not only for fun dame ntal researches but also for functional electronic and optoelectronic deviceapplications. | Xueping Wu Xiao Wang Honglai Li Zhouxiaosong Zeng Biyuan Zheng Danliang Zhang Fang Li Xiaoli Zhu Ying Jiang Anlian Pan | 2019 | Nano Research2019，12，12： | 3 |
| 3 | Synthesis and Diameter-dependent Thermal Conductivity of InAs Nanowires显示文摘In this work, we synthesized high-quality In As nanowires by a convenient chemical vapor deposition method,and developed a simple laser heating method to measure the thermal conductivity of a single In As nanowire in air. During the measurement, a focused laser was used to heat one end of a freely suspended nanowire, with its other end embedded into a carbon conductive adhesive. In order to obtain the thermal conductivity of In As nanowires, the heat loss in the heat transfer process was estimated, which includes the heat loss through air conduction, the heat convection, and the radiation loss. The absorption ratio of the laser power in the In As nanowire was calculated. The result shows that the thermal conductivity of In As nanowires monotonically increases from 6.4 W m-1K-1to 10.5 W m-1K-1with diameters increasing from 100 nm to 190 nm, which is ascribed to the enhanced phonon-boundary scattering. | Pinyun Ren Xiaoli Zhu Jinyun Han Jinyou Xu Liang Ma Honglai Li Xiujuan Zhuang Hong Zhou Qinglin Zhang Minggang Xia Anlian Pan | 2014 | Nano-Micro Letters2014，6，4： | 2 |

| 6 | CO_(2) capture and in-situ conversion: recent progresses and perspectives显示文摘Global warming caused by excess carbon dioxide(CO_(2))emission has been a focus of the world.The development of neutral carbon technologies becomes a strategic choice for the sustainable human society.Integrating CO_(2) capture and conversion(iCCC)technology can simultaneously convert the captured CO_(2) from flue gas into value-added chemicals,which saves great energies and expenses incurred in CO_(2) compression and transportation processes of conventional carbon capture,utilization,and storage(CCUS)technology.The present review criti-cally discusses the dual-function materials(DFMs)and the iCCC technology at intermediate temperature for methane production and high temperature for syngas production.The design of reactor and optimization of operation conditions are emphasized from the perspective of industrial applications.The dual-fixed-bed reactors mode by switching the flue gas and reactant gases,and the dual-fluidized-bed reactors mode by the circulation of DFMs particles are comparatively reviewed.We hope this review can stimulate further studies including designing and fabricating feasible DFMs,exploring realistic catalytic process for CO_(2) conversion to high value-added chemicals,developing workable reactor modes and optimizing operation conditions,and establishing industrial demonstration for real applications of iCCC technology in the future. | Bin Shao Yun Zhang Zheyi Sun Jianping Li Zihao Gao Zhicheng Xie Jun Hu Honglai Liu | 2022 | Green Chemical Engineering2022，3，3： | 2 |
| 7 | Modeling of Surface Tension and Viscosity for Non-electrolyte Systems by Means of the Equation of State for Square-well Chain Fluids with Variable Interaction Range显示文摘The equation of state(EOS)for square-well chain fluid with variable range(SWCF-VR) developed in our previous work based on statistical mechanical theory for chemical association is employed for the correlations of surface tension and viscosity of common fluids and ionic liquids(ILs).A model of surface tension for multi-component mixtures is presented by combining the SWCF-VR EOS and the scaled particle theory and used to produce the surface tension of binary and ternary mixtures.The predicted surface tensions are in excellent agreement with the experimental data with an overall average absolute relative deviation(AAD)of 0.36%.A method for the calculation of dynamic viscosity of common fluids and ILs at high pressure is presented by combining Eyring’s rate theory of viscosity and the SWCF-VR EOS.The calculated viscosities are in good agreement with the experimental data with the overall AAD of 1.44% for 14 fluids in 84 cases.The salient feature is that the molecular parameters used in these models are self-consistent and can be applied to calculate different thermodynamic properties such as pVT,vapor-liquid equilibrium,caloric properties,surface tension,and viscosity. | LI Jinlong HE Changchun MA Jun PENG Changjun LIU Honglai HU Ying | 2011 | Chinese Journal of Chemical Engineering2011，19，4： | 1 |

| 12 | IMPROVEMENT OF THE PERFORMANCE OF THE DISPENSER CATHODE WITH Re AS A MIDDLE LAYER显示文摘A new type of dispenser cathode with dual-layer (Os-W/Re) is developed. The cathode coated with Os-W/Re shows better emission performance than the cathode coated with Os-W alloy. X-ray Photoelectron Spectroscopy (XPS) spectra demonstrate that ternary alloy coating (Os-W-Re) formed on the surface of the cathode with dual-layer (Os-W/Re) after full activation is the major reason why it has better emission than the cathode with Os-W alloy. The surface of each variety of the cathode is characterized with Scanning Electron Microscope (SEM) before and after activation: the emitting surface of the cathode with Os-W alloy after ageing appeared non-adherence (flaking) in localized areas, which is one of the reasons for non-uniform emission. However, the surface of the cathode with dual-layer (Os-W/Re) does not present film peeling under the same conditions. Thus it ensures better emission uniformity and functional reliability for the dispenser cathode. | Li Yutao Zhang Honglai Liu Pukun Zhang Mingchen | 2006 | Journal of Electronics(China)2006，23，3： | 0 |

| 14 | Operando generated copper‐based catalyst enabling efficient electrosynthesis of 2,5‐bis(hydroxymethyl)furan显示文摘Electrocatalytic upgrading of biomass-derived platform molecules has emerged as a sustainable and environmentally benign route to produce high-value chemicals.The main challenge lies in developing efficient catalysts for the selective activation of designated chemical bonds in the presence of various reducible groups.This work demonstrated a high-efficiency electrochemical conversion of 5-hydroxymethylfurfural(HMF)to 2,5-bis(hydroxymethyl)furan(BHMF),an important industrial synthetic reagent.A highly porous Cu-based catalyst was developed that achieved nearly 100%BHMF selectivity and long-term stability.Through comprehensive operando and ex-situ structural characterizations,an electrochemically generated catalyst with abundant Cu/Cu2O interfaces was identified as a catalytically active phase for HMF conversion.Deuterated BHMF,with the potential to produce deuterated drugs,was also synthesized using D2O as the deuterium source.Density functional theory calculations show that the Cu/Cu2O interface structure exhibits relatively low energy barriers for the hydrogenation of HMF to BHMF.This work provides insights into the origin of electrocatalytic hydrogenation activity and highlights the promising potential of the electrocatalytic synthesis of high-value chemicals. | Zhaolu Zhang Kai Huang Xinyue Qiu Wangxin Ge Xiaoling Yang Yihua Zhu Cheng Lian Honglai Liu Hongliang Jiang Chunzhong Li | 2023 | Fundamental Research2023，3，5： | 0 |
| 15 | Multivalence-Ion Intercalation Enables Ultrahigh 1T Phase MoS_(2)Nanoflowers to Enhanced Sodium-Storage Performance显示文摘Developing rapid charging and robust electrode materials for Na-ion batteries is of considerable significance in large-scale power electricity fields.Herein,the authors have proposed a multivalenceion intercalation strategy to construct threedimensional(3D)Co-MoS2 nanoflowers with tailorable 1T/2H phase and interlayer distance.The as-formed S-Co-S covalent bonds serve as“electric bridges”to accelerate interlayer charge transfer without 1T phase degeneration during sodiation and desodiation.Quantum density functional theory(QDFT)calculations further confirm that the optimal Co-MoS2 nanoflowers possess the highest Na adsorption energy with reduced ionic diffusion barrier.Consequently,they deliver a superior sodiumstorage capacity of 351 mAh g−1 in 0.4-3.0 V even at 20 A g−1 without capacity fading at 5 A g−1 for 2000 cycles.The high electrochemical reversibility of the 1T phase in Co-MoS2,which accounts for such excellent performance,has been unveiled for the first time by in situ Raman spectra.This finding demonstrates important insights onto promoting two-dimensional(2D)nanomaterials toward rapid charging alkali-ion batteries. | Kun Ma Yu Liu Hao Jiang Yanjie Hu Rui Si Honglai Liu Chunzhong Li | 2021 | CCS Chemistry2021，3，5： | 0 |
| 16 | Van der Waals epitaxial growth and optoelectronics of a vertical MoS_(2)/WSe_(2)p-n junction显示文摘Two-dimensional(2D)transition metal dichalcogenides(TMDs)have attracted extensive attention due to their unique electronic and optical properties.In particular,TMDs can be fexibly combined to form diverse vertical van der Waals(vdWs)heterostructures without the limitation of lattice matching,which creates vast opportunities for fundamental investigation of novel optoelectronic applications.Here,we report an atomically thin vertical p-n junction WSe_(2)/MoS_(2)produced by a chemical vapor deposition method.Transmission electron microscopy and steady-state photoluminescence experiments reveal its high quality and excellent optical properties.Back gate feld efect transistor(FET)constructed using this p-n junction exhibits bipolar behaviors and a mobility of 9 cm^(2)/(V·s).In addition,the photodetector based on MoS_(2)/WSe_(2)heterostructures displays outstanding optoelectronic properties(R=8 A/W,D^(*)=2.93×10^(11)Jones,on/of ratio of 10^(4)),which benefted from the built-in electric feld across the interface.The direct growth of TMDs p-n vertical heterostructures may ofer a novel platform for future optoelectronic applications. | Yu Xiao Junyu Qu Ziyu Luo Ying Chen Xin Yang Danliang Zhang Honglai Li Biyuan Zheng Jiali Yi Rong Wu Wenxia You Bo Liu Shula Chen Anlian Pan | 2022 | Frontiers of Optoelectronics2022，15，4： | 0 |
| 17 | CO_2 capture through halogen bonding: A theoretical perspective显示文摘Halogen bonding interactions between several halogenated ion pairs and CO2 molecules have been investigated by means of density functional theory calculations. To account for the influence of solvent environment, the implicit polarized continuum model was also employed. The bromide and iodide cations of ionic liquids (ILs) under study can interact with CO2 molecules via X O interactions, which become much stronger in strength than those in the complexes of iodo-perfluorobenzenes, very effective halogen bond donors, with CO2 molecules. Such interactions, albeit somewhat weaker in strength, are also observed between halogenated ion pairs and CO2 molecules. Thus, the solubility of CO2 may be improved when using halogenated ILs, as a result of the formation of X O halogen bonds. Under solvent effects, the strength of the interactions tends to be weakened to some degree, with a concomitant elongation of intermolecular distances. The results presented here would be very useful in the design and synthesis of novel and potent ILs for CO2 physical absorption. | LI HaiYing LU YunXiang ZHU Xiang PENG ChangJun HU Jun LIU HongLai HU Ying | 2012 | Science China Chemistry2012，55，8： | 0 |
| 18 | Ionic Liquid-Polypyrrole-Gold Composites as Enhanced Enzyme Immobilization Platforms forHydrogen Peroxide Sensing显示文摘In this work, three different aqueous solutions containing imidazole-based ILs w让h different alkyl chain lengths ([Cnmim]Br, n = 2Z 6,12) were adopted as the medium for the synthesis of ionic liquid-polypyrrole (IL-PPy) composites. Herein, the ILs undertook the roles of the pyrrole solvent, the media for emulsion polymerization of PPy and PPy dopants, respectively. The electrochemical performances of the three IL-PPy composites on a glassy carbon electrode (GCE) were investigated by electrochemical experiments, which indicated that [Ci2mim]Br-PPy (Ci2~PPy) composites displayed better electrochemical performance due to their larger surface area and firmer immobilization on the GCE. Further, Ci2?PPy/GCE were decorated with Au microparticles by electrodeposition that can not only increase the conductivity, but also immobilize sufficient biomolecules on the electrode. Then, the obtained Ci2~PPy^Au/GCE with outstanding electrochemical performance was employed as a horseradish peroxidase (HRP) immobilization platform to fabricate a novel Ci2-PPy-Au-HRP/GCE biosensor for H2O2 detection. The results showed that the prepared Ci2-PPy-Au-HRP/GCE biosensor exhibited high sensitivity, fast response, and a wide detection range as well as low detection limit towards H2O2. This work not only provides an outstanding biomolecule immobilization matrix for the fabrication of highly sensitive biosensors, but also advances the understanding of the roles of ILs in improving the electrochemical performance of biosensors. | Meng Li Jing Wu Haiping Su Yazhuo Shang Yifan He Honglai Liu | 2019 | 北京日化2019，0，2： | 0 |
