摘要
Selective CO_(2) reduction to formate with highadded value is one of the most technologically and economically feasible pathways to realize electrochemical CO_(2) 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 CO_(2) to formate in aqueous electrolytes due to high-hydrogen evolution overpotential. Hence, bismuthbased catalysts are by far the most commercially available materials for electrochemical reduction of CO_(2) to formate.In this review, the electrochemical reduction of CO_(2) to formate over bismuth-based catalysts is elaborated. Firstly,this review describes performance evaluation indexes,evaluation systems and reaction mechanisms of the electrochemical reduction of CO_(2) to formate over bismuthbased catalysts. Subsequently, the research means to reveal the reaction mechanism of electrochemical reduction of CO_(2) to formate over bismuth-based catalysts and the performance improvement strategies of the reaction are described in detail. Finally, the opportunities and challenges in this encouraging field are discussed. We believe that this review will contribute to further development of electrochemical reduction of CO_(2) to formate over bismuthbased catalysts.
