Electrochemical reduction is considered as a promising means of CO2 utilization.It is crucial to develop an electrocatalyst that can increase the selectivity for high value-added products.Recently,carbon-based single-atom catalysts have shown great research value in electrocatalytic CO2 reduction reaction due to their high atom utilization and tunable chemical structure.This review introduces the reaction pathways of electrocatalytic CO2 reduction to various products.The catalytic performance for electrocatalytic CO2 reduction reaction over carbon-based single-atom catalysts with different metal species including Fe,Cu,Ni,Co,respectively is summarized.The effects of tuning strategies such as coordination environment tuning,electronic structure tuning,and active site number tuning on the catalytic performance and the reaction process are illustrated.In order to achieve better design and synthesis of carbon-based single-atom catalysts for the electrocatalytic CO2 reduction reaction,the strategies to improve the selectivity of the generated multi-carbon products and identify the true state of the active sites are discussed.
