双碳背景下电还原二氧化碳制甲酸用Bi基催化剂的研究与展望
Research and prospect of Bi-based catalyst for electroreduction of CO2 to formic acid under the background of double carbon
摘要
Abstract
[Objective]In order to improve the efficiency of electrocatalytic reduction of CO2 emitted by the thermal power industry to formic acid(HCOOH)and reduce the emission level of CO2 in the atmospheric environment,[Methods]In this paper,the improvement direction of high-efficiency Bi-based catalysts was proposed by analyzing the pathways of electrochemical carbon dioxide reduction reaction(ECO2RR)and the electrocatalytic effects of Bi metal-based catalysts under different control strategies.[Results]Studies have shown that Bi-based catalysts can achieve a Faraday efficiency greater than 85%when the stable operation time in the electrolytic cell is greater than 100 h.Bi-based ECO2RR catalysts can be regulated from four aspects:surface morphology design,surface modification,defect engineering and component regulation.The surface morphology design can provide more active sites,but it cannot meet the practical application requirements of commercial scale HCOOH production.Surface modification can have beneficial effects on selectivity and activity,but there are problems such as stability,cost and mechanism.Defect engineering can optimize the charge transfer in the reaction and the bonding strength of the intermediate,but the controllability and mechanism of defects need to be studied.Component regulation can be carried out from three aspects:Element doping,alloying,and heterostructure construction.It is an important way to optimize the Bi-based ECO2RR reaction,but it also needs to supplement the test and calculation that are more in line with industrial development.[Conclusion]Bi-based catalysts have outstanding potential in the industrial application of electroreduction of CO2 to HCOOH.More in-depth improvement and mechanism research can accelerate the industrialization of CO2-derived chemicals.关键词
