Electrocatalytic CO reduction reaction shows great potential for converting CO into high-value chemicals and fuels at normal temperature and pressure, combating climate change and achieving carbon neutrality goals. However, the complex reaction pathways involve the transfer of multiple electrons and protons, resulting in poor product selectivity, and the existence of competitive hydrogen evolution reactions further increases the associated difficulties. This review illustrates the research progress on the micro mechanism of electrocatalytic CO reduction reaction in the electrolyte environment in recent years. The reaction pathways of the products, pH effects, cation effects and anion effects were systematically summarized. Additionally, further challenges and difficulties were also pointed out. Thus, this review provides a theoretical basis and future research direction for improving the efficiency and selectivity of electrocatalytic CO reduction reaction.
电催化CO还原反应在常温常压下将CO转化为高价值化学品和燃料、应对气候变化以及实现碳中和目标方面显示出巨大潜力。然而，复杂的反应路径涉及多个电子和质子的转移，导致产物选择性较差，并且竞争性析氢反应的存在进一步增加了相关困难。本综述阐述了近年来在电解质环境中电催化CO还原反应微观机理的研究进展。系统总结了产物的反应路径、pH效应、阳离子效应和阴离子效应。此外，还指出了进一步的挑战和困难。因此，本综述为提高电催化CO还原反应的效率和选择性提供了理论基础和未来研究方向。
