摘　　要：金属铜(Cu)因电子电导率高、价格低廉和环境友好等优点,成为能源存储与转换领域的关键材料之一。然而,Cu因自身催化活性低和表面易腐蚀/氧化等,限制了其在电解水制氢领域的实际应用。通过对Cu进行改性,可优化电极表面对反应中间体的吸附和界面稳定性,显著提升催化性能。本文简要介绍了目前Cu基电极存在的问题,重点阐述了Cu基电极在单原子结构设计、Cu基复合材料、Cu合金化以及杂原子掺杂四方面的改性研究进展,并对析氢催化机理进行深入分析。结果表明,通过对Cu进行改性可以激活Cu位点、暴露更多活性面积和稳定界面,显著提高Cu基电极的催化活性和催化稳定性。未来,Cu催化电极的研究应注重更有效的材料改性方法,以便进一步提高其在催化反应中的应用价值。Metallic copper(Cu)has become one of the key materials in the field of energy storage and conversion due to its high elec‐tronic conductivity,low price,and environmental friendliness.However,the low catalytic activity and surface corrosion/oxidation of Cu limits its practical application in the field of hydrogen evolution reaction(HER)during water splitting.Modification of Cu by many strat‐egies can optimize adsorption of reaction intermediates and enhance interfacial stability,thus the catalytic performance can be signifi‐cantly improved.This paper briefly introduced the obstacles of Cu-based electrodes in HER application.Then the research progresses of Cu-based electrodes in the designation of single-atom structure,Cu-based composite materials,Cu alloying and heteroatom doping were summarized.The catalytic mechanisms of different catalysts during HER process were also analyzed in depth.The results showed that Cu site could be activated by modifying Cu,exposing more active area,and stabilizing the interface,during which the catalytic ac‐tivity and stability were significantly improved.To further improve the application value of Cu-based electrodes in catalytic reaction,the modification methods should be focused more attention.
