摘要
1.Introduction Carbon dioxide reduction(CO_(2)RR)technology has attracted much attention in recent years and can effectively decrease the greenhouse effect and simultaneously achieve chemical energy storage[1].In the electrochemical process,a large overpotential is generally required to activate inert CO_(2)molecules,resulting in the inevitable competition reaction from the hydrogen evolution reaction(HER)and consequently decreasing the faradaic efficiency of CO_(2)RR[2,3].Among various reduction products of CO_(2)RR,formate is the most prevalent product with important applications in the energy conversion and chemical industries.Among a host of catalysts that can convert CO_(2)to formate,bismuth(Bi)-based nanomaterials are highly promising electrocatalysts for the conversion of CO_(2)to formate due to their high faradaic efficiency and good stability.However,the preparation method and catalytic activity of Bi-based nanomaterials still need to be further improved for industrial conversion of the CO_(2)RR.
