| 2 | Cable-like carbon nanotubes decorated metal-organic framework derived ultrathin CoSe2/CNTs nanosheets for electrocatalytic overall water splitting显示文摘The high cost and low reserves of noble metals greatly hinder their practical applications in new energy production and conversion.The exploration of cost-effective alternative electrocatalysts with the ability to drive hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)is extremely significant to promote overall water splitting.Herein,ultrathin CoSe2/CNTs nanocomposites have been synthesized by a facile two-step method,where the ultrathin Co-MOF(metal organic-framework)decorated with cable-like carbon nanotubes(CNTs)(Co-MOF/CNTs)was initially fabricated,and followed a lowtemperature selenization process.The ultrathin CoSe2 nanosheets as well as the superior conductivity of CNTs synergistically resulted in abundant active sites and enhanced conductivity to boost the electrocatalytic activity.The as-prepared CoSe2/CNTs electrocatalysts exhibited an overpotential of190 mV and 300 mV vs.reversible hydrogen electrode(RHE)at a current density of 10 mA/cm^(2) for the HER and OER in alkaline solution,respectively,and demonstrated superior durability.Furthermore,the as-prepared bifunctional CoSe2/CNTs electrocatalysts can act as cathode and anode in an electrolyzer,showing a cell voltage of 1.75 V at 10 mA/cm^(2) for overall water splitting. | Guijuan Wei Kun Du Xixia Zhao Jiayang Wang Wenxiu Yan Chao An Changhua An | 2020 | Chinese Chemical Letters2020，31，10： | 5 |
| 3 | FeNi nanoparticles on Mo_(2)TiC_(2)T_(x)MXene@nickel foam as robust electrocatalysts for overall water splitting显示文摘The development of cost-effective electrocatalysts for overall water splitting is highly desirable,remaining a critical challenge at current stage.Herein,a class of composite FeNi@MXene(Mo_(2)TiC_(2)T_(x))@nickel foam(NF)has been synthesized through introducing Fe2+ions and in-situ combining with surface nickel atoms on nickel foam.The obtained FeNi@Mo_(2)TiC_(2)T_(x)@NF exhibited high activity with overpotentials of 165 and 190 mV for the hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)at a current density of 10 mA·cm^(-2),respectively.The synergetic effects of Mo_(2)TiC_(2)T_(x)and FeNi nanoalloys lead to increasing catalytic activities,where MXene provides high active surface area and rich active sites for HER,and FeNi nanoalloys promote the OER.Theoretical simulation of electron exchange capacity between FeNi and MXene in FeNi@Mo_(2)TiC_(2)T_(x)catalyst shows that electrons transferred from surface Mo atoms to the interface between FeNi and MXene,indicating that the electrons are accumulated near the FeNi nanoparticles.This kind of electronic distribution facilitates the formation of intermediate of NiOOH.Correspondingly,(H++e-)is more inclined onto Mo-Ni interfaces for HER.The Gibbs free energy changes for H*to HER and potential-limiting step for-OOH intermediate in OER over FeNi@Mo_(2)TiC_(2)T_(x)are much less than those on bare MXene.The catalyst can be further used for overall water splitting in alkaline solution,realizing a current density of 50 mA·cm^(-2)at 1.74 V.This work provides a facile strategy to achieve efficient and cheap catalysts for new energy production. | Jiayang Wang Peilei He Yongli Shen Linxiu Dai Zhe Li Yue Wu Changhua An | 2021 | Nano Research2021，14，10： | 5 |
| 4 | Carbon quantum dot-induced self-assembly of ultrathin Ni(OH)2 nanosheets: A facile method for fabricating three-dimensional porous hierarchical composite micro-nanostructures with excellent supercapacitor performance显示文摘Significant efforts have been directed towards the preparation and applicationof porous hierarchically structured materials owing to their large surface area,rich active sites, and enhanced mass transport and diffusion. In this study, asimple and cost-effective method for the carbon quantum dot (CQD)-inducedassembly of two-dimensional ultrathin Ni(OH)2 nanosheets into a three-dimensional (3D) porous hierarchical structure was developed. The electrostaticforces between the CQDs and cations drove the self-assembly of the 3DCQDs/Ni(OH)2 hierarchical structures. As a new type of structure-directingagent, the CQDs played dual roles in tuning the morphology of the productsand improving the supercapacitor performance. The multilevel CQDs/Ni(OH)2micro-nanostructures had a large specific surface area and rich porosity. Owingto their unique structures and the conductivity of the CQDs, an optimizedasymmetric supercapacitor using the CQDs/Ni(OH)2 exhibited a maximumspecific capacity of 161.3 F.g-1 and a high energy density of 57.4 Wh·kg^-1 Thisstudy introduces a potential method for the fabrication of many other 3Dhierarchical structures with great potential for applications in various fields. | Guijuan Wei Kun Du Xixia Zhao Zhaojie Wang Ming Liu Chuang Li Hui Wang Changhua An Wei Xing | 2017 | Nano Research2017，10，9： | 4 |
| 5 | Oil-soluble Ni-Mo sulfide nanoparticles and their hydrogenation catalytic properties显示文摘Oil-soluble bimetallic Ni-Mo sulfide nanoparticles(NiMoS) with narrow size distribution were successfully synthesized through a composite-surfactants-assisted-solvothermal process.The surface functionality and lipophilicity of the Ni-Mo sulfides were shown by transmission electronic microscopy,Fourier transform infrared and ultraviolet spectroscopy.The as-prepared Ni-Mo sulfides supported on activated carbon(NiMoS/AC) exhibited enhanced catalytic activity towards naphthalene hydrogenation instead of cracking.For comparison,CoMoS/AC and MoS2/AC catalysts were also prepared through similar procedures,and it was found that their catalytic performance decreased in the order of NiMoS/AC>CoMoS/AC>MoS2/AC.Furthermore,the activity of the bimetallic NiMoS nanocatalyst can be effectively tuned via variation of the atomic ratio of Ni/(Ni+Mo). | Liu Chenguang Wang Shutao An Changhua Yan Fang He Jie Wang Zongxian Zhang Qin-Hui | 2013 | Petroleum Science2013，10，4： | 2 |

| 17 | Facile preparation of efficient oil-soluble MoS_2 hydrogenation nanocatalysts显示文摘Oil-soluble MoS2 nanoparticles with narrow size distribution have been synthesized by a facile composite-surfactants-aided-solvothermal process.The as-prepared nanoparticles can be directly used as hydrogenation nanocatalysts or as precursors to achieve efficient supported nanocatalysts.The surfaces of these nanoparticles are proposed to be encapsulated within a layer of organic modifiers,which are responsible for the enhancement of their solubility in organic solvents.The activated-carbon supported MoS2 nanocatalysts exhibit higher activity than the unsupported ones towards hydrogenation reactions of naphthalene,owing to the synergistic effects between nanoparticles and supports.The advantages of the present nanocatalysts,such as removal of conventional presulfiding requirements and reduction of nanoparticle aggregations,make them become promising applications in related petroleum chemical industry. | Shutao Wang Changhua An Jie He Zongxian Wang | 2011 | Journal of Natural Gas Chemistry2011，20，4： | 1 |

| 20 | Surface-tuning nanoporous AuCu_(3) engineering syngas proportion by electrochemical conversion of CO_(2)显示文摘The direct electrochemical conversion of CO_(2) to syngas with controllable composition remains challenging. In this work, driven by concentration gradient, a simple air-heating aided strategy has been developed to adjust surface composition of the self-supporting nanoporous AuCu_(3) alloy. According to Fick First Law, the interior Cu atoms of the AuCu_(3) alloy with Au-rich surface gradually segregated outwards during heating, realizing Cu-rich surface eventually. Correspondingly, the competing electrocatalytic CO_(2) reduction (ECR) to CO and hydrogen evolution reactions (HER) were tactfully balanced on these alloy surfaces, thus achieving proportion-tunable syngas (CO/H2). Density functional theory (DFT) calculations on the Gibbs free energy change of the COOH* and H* (ΔGCOOH*, ΔGH*) on the alloy surfaces were conducted, which are generally considered as the selectivity descriptors for CO and H2 products, respectively. It shows ΔGCOOH* gradually increases in contrast to the decreased ΔGH* with more Cu on the surface, suggesting H2 is more favored over Cu sites, which is consistent with the declining CO/H2 ratio observed in the experiments. This study reveals that the surface composition controls ECR activity of nanoporous AuCu_(3) alloy, providing an alternative way to the syngas production with desirable proportion. | Chao An Yongli Shen Wenxiu Yan Linxiu Dai Changhua An | 2021 | Nano Research2021，14，11： | 1 |
