| 6 | Reactivity of hydrogen species on oxide surfaces显示文摘Hydrogen species on oxides are widely involved in oxides-catalyzed reactions such as H_2/hydrocarbon oxidation, hydrogenation/dehydrogenation, water-gas shift, and water-splitting reactions. Thus identifications of hydrogen species on oxide surfaces and their reactivity are important for fundamental understanding of these oxides-catalyzed reactions. In this Feature Article, we briefly review our research progress on the reactivity of various hydrogen species on oxides, including surface hydroxyl species,hydride species and hydrated protons. We have successfully developed effective strategies of using gas-phase atomic H to controllably create oxygen vacancies and prepare various hydrogen species on oxide model catalysts under ultra-high vacuum(UHV) conditions and using well-defined oxide nanocrystals with different surface structures and oxygen vacancy concentrations to study the H_2-oxide interaction under ambient or even higher H_2 pressures. Reactivity of various hydrogen species on oxide surfaces has been identified, including local oxygen vacancy-controlled reactivity of OH species, oxygen vacancystabilized hydride species, homolytic dissociation of H2 at oxygen vacancies of reduced oxide surfaces into hydride species accompanied by surface oxidation, photoexcited holes-stimulated desorption of hydride species, electron-stimulated desorption of hydride and OH species, and photoexcited electrons-stimulated desorption of hydrated protons. Strong influences of oxygen vacancies in oxides on both stability and reactivity of various hydrogen species on oxide surfaces are highlighted. | Zhaorui Li Weixin Huang | 2021 | Science China Chemistry2021，64，7： | 3 |
| 7 | Thermal-, photo- and electron-induced reactivity of hydrogen species on rutile TiO_2(110) surface: Role of oxygen vacancy显示文摘Interaction of hydrogen with TiO_2 plays a vital role in TiO_2-based photocatalysis and thermal catalysis. In this work, we compared thermal-, photo-, and electron-induced reactivity of various types of hydrogen species on a rutile TiO_2(110) surface formed by atomic H exposure at 320 and 115 K by means of thermal desorption spectroscopy, X-ray photoelectron spectroscopy and low energy electron diffraction. Atomic H interaction with rutile TiO_2(110) at 115 K forms surface TiààH hydride, surface hydroxyl group, and chemisorbed water. Upon heating, surface TiààH hydride reacts to produce H2 while surface hydroxyl groups react to form both water and H2. Atomic H interaction with rutile TiO_2(110) at 320 K strongly reduces TiO_2 due to the continuous formation and desorption of water and forms surface hydroxyl groups and likely subsurface/bulk hydrogen species. Upon heating, hydrogen forms as the only gas-phase product and its desorption activation energy decreases with the subsurface/bulk reduction extent of rutile TiO_2(110). Surface Ti-H hydride exhibits photo-induced reactivity while both surface TiààH hydride and surface hydroxyl group exhibit electro-induced reactivity. These results have important implications for understanding the hydrogen-involved thermal and photo reactions on TiO_2-based catalysts. | Zongfang Wu Feng Xiong Zhengming Wang Weixin Huang | 2018 | Chinese Chemical Letters2018，29，6： | 2 |
| 8 | Two Ultraviolet Radiation Datasets that Cover China显示文摘Ultraviolet(UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes. | Hui LIU Bo HU Yuesi WANG Guangren LIU Liqin TANG Dongsheng JI Yongfei BAI Weikai BAO Xin CHEN Yunming CHEN Weixin DING Xiaozeng HAN Fei HE Hui HUANG Zhenying HUANG Xinrong LI Yan LI Wenzhao LIU Luxiang LIN Zhu OUYANG Boqiang QIN Weijun SHEN Yanjun SHEN Hongxin SU Changchun SONG Bo SUN Song SUN Anzhi WANG Genxu WANG Huimin WANG Silong WANG Youshao WANG Wenxue WEI Ping XIE Zongqiang XIE Xiaoyuan YAN Fanjiang ZENG Fawei ZHANG Yangjian ZHANG Yiping ZHANG Chengyi ZHAO Wenzhi ZHAO Xueyong ZHAO Guoyi ZHOU Bo ZHU | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |

| 10 | Fast and highly reversible Na^(+)intercalation/extraction in Zn/Mg dual-doped P2-Na_(0.67)MnO_(2)cathode material for high-performance Na-ion batteries显示文摘P2-type layered Na_(0.67)MnO_(2)has been considered to be a promising candidate cathode material for sodium ion batteries.Nevertheless,the undesired phase transitions during operation and the large Na^(+)radius induced sluggish ion diffusion remain the stumbling blocks to realize its high performance.Herein,we propose a Zn/Mg co-doping strategy,which is proved to have bifunctional effects.First,relative to the pristine P2-Na_(0.67)MnO_(2)and the single-ion(Zn/Mg)doped samples,the Zn/Mg dual-doped P2-Na_(0.67)MnO_(2)demonstrates a lower Mn^(3+)/Mn^(4+)ratio and a higher lattice O content,which facilitate the structural stability of the cathode material.More intriguingly,the Zn/Mg co-doping gives rise to enlarged interplanar spacing,which provides spacious ion diffusion channels for fast Na^(+)intercalation/extraction.As a result,the Zn/Mg dual-doped sample exhibits a high Na^(+)diffusion coefficient and a solid-solution reaction during charge/discharge,with a cell volume change determined to be only 0.55%.Taking advantages of the above favorable features,the Zn/Mg dual-doped P2-Na_(0.67)MnO_(2)demonstrates a high rate performance with 67.2 mAh·g^(-1)delivered at 10 C and a decent cycling stability with a capacity retention of 93.8%achieved at 1 C after 100 cycles.This work introduces the Zn/Mg co-doping strategy to simultaneously improve the cycling stability and rate capability of P2-Na_(0.67)MnO_(2),which may offer a promising avenue for further performance enhancement of the layered Na-ion batteries cathode materials. | Xiaoqin Huang Deli Li Haijian Huang Xiao Jiang Zeheng Yang Weixin Zhang | 2021 | Nano Research2021，14，10： | 2 |
| 11 | Structure-design and theoretical-calculation for ultrasmall Co_(3)O_(4) anchored into ionic liquid modified graphene as anode of flexible lithium-ion batteries显示文摘Cobalt oxide(Co_(3)O_(4))is currently suitable in energy storage applications because of its high capacity based on the conversion reaction mechanism.However,unmodified Co_(3)O_(4)suffers from distinctly inferior rate capability and poor cycling stability.On the basis of the aforementioned considerations and density functional theory(DFT)simulations,the three-dimensional hierarchical porous structure(HPS)ultrasmall Co_(3)O_(4)anchored into ionic liquid(IL)modified graphene oxide(GO)has been successfully prepared(ultrasmall/Co_(3)O_(4)-GA-IL).The ultrasmall/Co_(3)O_(4)-GA-IL consists of Co_(3)O_(4)co-assembled with IL modified GO to generate the HPS which can facilitate ion transfer channels through reduction of the electron and ion transportation path and transmission impedance.In addition,N-doping graphene can enhance the inherent electrical conductivity of Co_(3)O_(4),which is proved by the DFT calculations.By virtue of the novel superstructure,the ultrasmall/Co_(3)O_(4)-GA-IL electrode demonstrates a high reversible capacity of 1,304 mAh·g^(−1),an enhanced high-rate capability(715 mAh·g^(−1)at 5 C),and a capacity retention of 98.4%even after 500 cycles at 5 C rate,which corresponds to 0.0003%capacity loss per cycle.Pouch cells based on the cathode are further fabricated and demonstrate excellent mechanical and electrochemical properties under bent and folded state,highlighting the practical application of our deliberately designed electrode in wearable electronics. | Longda Cong Shichao Zhang Hengyao Zhu Weixin Chen Xueyan Huang Yalan Xing Jun Xia Puheng Yang Xia Lu | 2022 | Nano Research2022，15，3： | 1 |

| 13 | Delaminating Ti3C2 MXene by blossom of ZnIn2S4 microflowers for noble-metal-free photocatalytic hydrogen production显示文摘Herein,a novel strategy was exploited to achieve the delamination of TiCMXene multilayers into ultrathin flakes by blossom of ZnInSmicroflowers via a one-pot solvothermal method.There is no need to peel off the MXene bulk ahead of its combination with the semiconductor.The obtained ZnInS/TiCbinary composites were applied for visible-light-driven photocatalytic hydrogen production without noble metal cocatalyst,and the optimized sample exhibited a hydrogen-production efficiency of 978.7 μmol hgwith the corresponding apparent quantum efficiency of 24.2% at 420 nm,which was 2.7 times higher than bare ZnInS.Through the comprehensive analysis based on spectroscopy measurements,electrochemical techniques and energy band theory,such enhancement was mainly attributed to(1) the highly-exposed surface that was beneficial for the adequate exposure of reactive sites and(2)the intimate contact interface that favored the transfer of photogenerated carriers.This study provides a new way of thinking for synthesizing ultrathin MXene-based composite materials for noble-metal-free and highly-efficient photocatalysis applications. | Weixin Huang Zhipeng Li Chao Wu Hanjie Zhang Jie Sun Qin Li | 2022 | Journal of Materials Science & Technology2022，，25： | 1 |

| 18 | Development of low-coherence high-power laser drivers for inertial confinement fusion显示文摘The use of low-coherence light is expected to be one of the effective ways to suppress or even eliminate the laser–plasma instabilities that arise in attempts to achieve inertial confinement fusion.In this paper,a review of low-coherence high-power laser drivers and related key techniques is first presented.Work at typical low-coherence laser facilities,including Gekko XII,PHEBUS,Pharos III,and Kanal-2 is described.The many key techniques that are used in the research and development of low-coherence laser drivers are described and analyzed,including low-coherence source generation,amplification,harmonic conversion,and beam smoothing of low-coherence light.Then,recent progress achieved by our group in research on a broadband low-coherence laser driver is presented.During the development of our low-coherence high-power laser facility,we have proposed and implemented many key techniques for working with low-coherence light,including source generation,efficient amplification and propagation,harmonic conversion,beam smoothing,and precise beam control.Based on a series of technological breakthroughs,a kilojoule low-coherence laser driver named Kunwu with a coherence time of only 300 fs has been built,and the first round of physical experiments has been completed.This high-power laser facility provides not only a demonstration and verification platform for key techniques and system integration of a low-coherence laser driver,but also a new type of experimental platform for research into,for example,high-energy-density physics and,in particular,laser–plasma interactions. | Yanqi Gao Yong Cui Lailin Ji Daxing Rao Xiaohui Zhao Fujian Li Dong Liu Wei Feng Lan Xia Jiani Liu Haitao Shi Pengyuan Du Jia Liu Xiaoli Li Tao Wang Tianxiong Zhang Chong Shan Yilin Hua Weixin Ma Xun Sun Xianfeng Chen Xiuguang Huang Jian Zhu Wenbing Pei Zhan Sui Sizu Fu | 2020 | Matter and Radiation at Extremes2020，5，6： | 1 |

| 20 | Morphology-dependent structures and catalytic performances of Au nanostructures on Cu_2O nanocrystals synthesized by galvanic replacement reaction显示文摘Au nanostructures were prepared on uniform Cu_2O octahedra and rhombic dodecahedra via the galvanic replacement reaction between HAu Cl4 and Cu2O. The compositions and structures were studied by Scanning Electron Microscope(SEM), Transmission Electron Microscope(TEM), High-Resolution Transmission Electron Microscope(HRTEM), X-Ray Diffraction(XRD), X-Ray Absorption Spectroscopy(XAS), X-ray Photoelectron Spectroscopy(XPS) and in-situ DRIFTS spectroscopy of CO adsorption. Different from the formation of Au–Cu alloys on Cu_2O cubes by the galvanic replacement reaction(Chem Nano Mat 2(2016)861-865), metallic Au particles and positively-charged Au clusters form on Cu_2O octahedra and rhombic dodecahedra at very small Au loadings and only metallic Au particles form at large Au loadings. Metallic Au particles on Cu_2O octahedra and rhombic dodecahedra are more active in catalyzing the liquid phase aerobic oxidation reaction of benzyl alcohol than positively-charged Au clusters. These results demonstrate an obvious morphology effect of Cu_2O nanocrystals on the liquid–solid interfacial reactions and prove oxide morphology as an effective strategy to tune the surface reactivity and catalytic performance. | Zhenhua Zhang Rui Song Tian Cao Weixin Huang | 2016 | Journal of Energy Chemistry2016，25，6： | 1 |
