Selective CO2 reduction to formate with high-added value is one of the most technologically and eco-nomically feasible pathways to realize electrochemical CO2 fixation.Bismuth-based catalysts have the advantages of nontoxicity,low cost,high abundance,as well as excellent stability.In addition,bismuth-based catalysts display excellent selectivity for the electrochemical reduction of CO2 to formate in aqueous electrolytes due to high-hydrogen evolution overpotential.Hence,bismuth-based catalysts are by far the most commercially available materials for electrochemical reduction of CO2 to formate.In this review,the electrochemical reduction of CO2 to formate over bismuth-based catalysts is elaborated.Firstly,this review describes performance evaluation indexes,evaluation systems and reaction mechanisms of the elec-trochemical reduction of CO2 to formate over bismuth-based catalysts.Subsequently,the research means to reveal the reaction mechanism of electrochemical reduction of CO2 to formate over bismuth-based catalysts and the per-formance improvement strategies of the reaction are described in detail.Finally,the opportunities and chal-lenges in this encouraging field are discussed.We believe that this review will contribute to further development of electrochemical reduction of CO2 to formate over bismuth-based catalysts.
