| 1 | Iron-group electrocatalysts for ambient nitrogen reduction reaction in aqueous media显示文摘Electrochemical nitrogen reduction reaction(NRR)is considered as an alternative to the industrial Haber-Bosch process for NH3 production due to both low energy consumption and environment friendliness.However,the major problem of electrochemical NRR is the unsatisfied efficiency and selectivity of electrocatalyst.As one group of the cheapest and most abundant transition metals,iron-group(Fe,Co,Ni and Cu)electrocatalysts show promising potential on cost and performance advantages as ideal substitute for traditional noble-metal catalysts.In this minireview,we summarize recent advances of iron-group-based materials(including their oxides,hydroxides,nitrides,sulfides and phosphides,etc.)as non-noble metal electrocatalysts towards ambient N2-to-NH3 conversion in aqueous media.Strategies to boost NRR performances and perspectives for future developments are discussed to provide guidance for the field of NRR studies. | Benyuan Ma Haitao Zhao Tingshuai Li Qian Liu Yongsong Luo Chengbo Li Siyu Lu Abdullah M.Asiri Dongwei Ma Xuping Sun | 2021 | Nano Research2021，14，3： | 8 |
| 2 | Electrocatalytic N_(2) reduction to NH3 with high Faradaic efficiency enabled by vanadium phosphide nanoparticle on V foil显示文摘To develop highly efficient electrochemical catalysts for N2 fixation is important to sustainable ambient NH_(3) production through the N_(2) reduction reaction(NRR).Herein,we demonstrate the development of vanadium phosphide nanoparticle on V foil as a high-efficiency and stable catalyst for ambient NH3 production with excellent selectivity.The high Faradaic efficiency of 22%with a large NH3 yield of 8.35×10^(−11) mol·s^(−1)·cm^(−2)was obtained at 0 V vs.the reversible hydrogen electrode in acid solution,superior to all previously studied V-based NRR catalysts.Density functional theory calculations are also utilized to have an insight into the catalytic mechanism. | Peipei Wei Qin Geng Ali Imran Channa Xin Tong Yongsong Luo Siyu Lu Guang Chen Shuyan Gao Zhiming Wang Xuping Sun | 2020 | Nano Research2020，13，11： | 4 |
| 3 | Working-in-tandem mechanism of multi-dopants in enhancing electrocatalytic nitrogen reduction reaction performance of carbon- based materials显示文摘Developing carbon-based electrocatalysts with excellent N2 adsorption and activation capability holds the key to achieve highly efficient nitrogen reduction reaction(NRR)for reaching its practical application.Here,we report a highly active electrocatalyst--metal-free pyrrolic-N dominated N,S co-doped carbon(pyrr-NSC)for NRR.Based on theoretical and experimental results,it is confirmed that the N and S-dopants practice a working-in-tandem mechanism on pyrr-NSC,where the N-dopants are utilized to create electropositive C sites for enhancing N2 adsorption and the S-dopants are employed to induce electron backdonation for facilitating N2 activation.The synergistic effect of the pyrrolic-N and S-dopants can also suppress the irritating hydrogen evolution reaction,further boosting the NRR performance.This work gives an indication that the combination of two different dopants on electrocatalyst can enhance NRR performance by working in the two tandem steps-the adsorption and activation of N2 molecules,providing a new strategy for NRR electrocatalyst design. | Wenqing Zhang Keke Mao Jingxiang Low Hengjie Liu Yanan Bo Jun Ma Qiaoxi Liu Yawen Jiang Jiuzhong Yang Yang Pan Zeming Qi Ran Long Li Song Yujie Xiong | 2021 | Nano Research2021，14，9： | 2 |
