摘要

Abstract

Solving the problems of carbon dioxide(CO2)emis-sions and energy scarcity by the development of highly selective,cost-effective,and reliable catalysts for the electrochemical reduc-tion of CO2 to useful carbon-based products would be very helpful.We report the synthesis of an efficient graphene-supported bismuth single-atom catalyst(BiSA-G)featuring a BiN4 coordination struc-ture for this purpose.The synthesis used tannic acid as a multifunc-tional ligand and ammonia as a nitrogen dopant.Using a scalable coordination chemistry approach,BiN4 sites were uniformly dis-persed on the graphene substrate and were found to have an out-standing ability for the conversion of CO2 to CO,with a high Fara-daic efficiency of 97.4%at-0.55 V(vs.RHE)and a high turnover frequency of 5230 h-1 along with outstanding stability.Density functional theory calculations confirmed that the BiN4 site serves as the dominant active center,simultaneously facilit-ating CO2 activation and the efficient formation of the crucial intermediate*COOH with a reduced free energy barrier.This dis-covery offers a new way for the atomic-scale design of high-efficiency catalysts for the electrochemical CO2 reduction reaction,potentially helping sustainable carbon use.
