| 1 | MOF-Transformed In_(2)O_(3-x)@C Nanocorn Electrocatalyst for Efficient CO_(2)Reduction to HCOOH显示文摘For electrochemical CO_(2) reduction to HCOOH,an ongoing challenge is to design energy efficient electrocatalysts that can deliver a high HCOOH current density(JHCOOH)at a low overpotential.Indium oxide is good HCOOH production catalyst but with low con-ductivity.In this work,we report a unique corn design of In_(2)O_(3-x)@C nanocatalyst,wherein In_(2)O_(3-x)nanocube as the fine grains dispersed uniformly on the carbon nanorod cob,resulting in the enhanced conductivity.Excellent performance is achieved with 84%Faradaic efficiency(FE)and 11 mA cm^(−2)JHCOOH at a low potential of−0.4 V versus RHE.At the current density of 100 mA cm^(−2),the applied potential remained stable for more than 120 h with the FE above 90%.Density functional theory calculations reveal that the abundant oxygen vacancy in In_(2)O_(3-x) has exposed more In^(3+) sites with activated electroactivity,which facilitates the formation of HCOO*intermediate.Operando X-ray absorp-tion spectroscopy also confirms In^(3+) as the active site and the key intermediate of HCOO*during the process of CO_(2) reduction to HCOOH. | Chen Qiu Kun Qian Jun Yu Mingzi Sun Shoufu Cao Jinqiang Gao Rongxing Yu Lingzhe Fang Youwei Yao Xiaoqing Lu Tao Li Bolong Huang Shihe Yang | 2022 | Nano-Micro Letters2022，14，10： | 2 |
| 2 | How can the Dual-atom Catalyst FeCo-NC Surpass Singleatom Catalysts Fe-NC/Co-NC in CO_(2) RR?-CO Intermediate Assisted Promotion via a Synergistic Effect显示文摘Atomically dispersed catalysts are widely adopted in CO_(2)reduction reaction(CO_(2)RR)due to maximal atomic utilization and high catalytic activity.Dual-atom catalysts(DACs),with more dispersed active sites and distinct electronic structures compared with single-atom catalysts(SACs),may exhibit diverse catalytic performance.Herein,the DAC FeCo-NC and SAC Fe-NC/Co-NC are employed as probes to explore DACs advantage in CO_(2)RR.Results show that the moderate interaction between the dual-atom center and N coordination balances structural stability and catalytic activity.CO is the only product on Fe-NC/Co-NC,and the high limiting potentials from−1.22 to−1.67 V inhibit further reduction.FeCo-NC assisted with CO intermediate exhibits low limiting potentials of−0.64 V for both CH_(3)OH and CH 4,comparable to those on Cu-based catalysts.Under circumstance of applied potentials,CO_(2)RR on FeCo-NC has greater advantages in yielding CH_(3)OH and CH 4 than that on Fe-NC/Co-NC,and hydrogen evolution reaction is severely inhibited.The intrinsic essence is that dual-atom center can provide large spin-polarization and multi-electron transfer capability,rendering CO intermediates as effective electronic and geometric modifiers in CO_(2)RR.This work highlights FeCo-NC as a high-performance CO_(2)RR catalyst toward deep-reduction C1 products and elucidates CO intermediate assisted promotion mechanism via a dual-atom synergistic effect. | Shoufu Cao Sainan Zhou Hongyu Chen Shuxian Wei Siyuan Liu Xiaojing Lin Xiaodong Chen Zhaojie Wang Wenyue Guo Xiaoqing Lu | 2023 | Energy & Environmental Materials2023，6，1： | 1 |

| 4 | Construction of pH-universal hydrogen evolution freeway in MoO_(3)-MoNi_(4)@Cu core-shell nanowires via synergetic electronic and geometric effect显示文摘Both the adsorption/dissociation of water molecules and hydrogen intermediate(H*)are the major limitations to hydrogen evolution reaction(HER).Herein,the modulation of electronic structure and geometric configuration are combined to design onedimensional electrocatalyst with outstanding HER activity in a wide pH range.The catalyst was composed of molybdenum trioxide doped molybdenum nickel alloy supported by copper nanowires(MoO_(3)-MoNi_(4)@Cu NWs).As revealed by the experimental characterizations and theoretical calculations,Cu NWs act as the electron donator to MoNi4,resulting in up shift of the d-band center in MoNi4,thus expediting H_(2)O adsorption and dissociation.Moreover,the introduction of amorphous MoO_(3) sets up a unique geometric configuration on MoNi4 for the accelerated H*transfer via hydrogen-bond and hydrogen spillover.This work provides a synergetic route for constructing HER freeway and promotes further investigations on more versatile electrocatalysis involving H_(2)O or H*. | Xiaodong Chen Shoufu Cao Xiaojing Lin Xiaofei Wei Zhaojie Wang Hongyu Chen Chengcheng Hao Siyuan Liu Shuxian Wei Daofeng Sun Xiaoqing Lu | 2023 | Nano Research2023，16，10： | 1 |

| 8 | Selectivity switching between CO and formate for CO_(2) reduction on Sb modified amorphous ZnO by electronic effect显示文摘The adjustable intermediate binding capacity in electrocatalytic carbon dioxide(CO_(2))reduction is critical for varying the reaction pathways to desired products.Herein,we first report the synthesis of boron-doped amorphous zinc oxide with(B-a-ZnO-Sb)or without antimony nanoparticles embedding(B-a-ZnO)via one-step wet chemical method,which is easy to scale up by enlarging the vessel and increasing feeding.Sb successfully realizes the product switching from CO on B-a-ZnO to formate on B-a-ZnOSb.Both experimental and theoretical results reveal that Sb weakens the charge interaction on Zn atoms.Based on the moderate adsorption of*COOH and strong adsorption of*OCHO and*HCOOH for B-a-ZnO,the foreign Sb weakens the adsorption of these intermediates and brings about a favor formate production instead of CO.This work points out a new direction for the synthesis of amorphous ZnO-based catalysts and provides advanced insights into the aimed selectivity switch for CO_(2)reduction by electronic effect. | Hongyu Chen Shoufu Cao Lu Wang Xiaojing Lin Qiuying Zhu Yizhu Shang Shuxian Wei Siyuan Liu Zhaojie Wang Baojun Wei Xiaoqing Lu | 2023 | Nano Research2023，16，10： | 0 |
