一步电还原法制备Cu-Sn合金催化剂实现高效电还原CO2制备甲酸盐
Fabrication of Cu-Sn alloy catalysts via one-step electrodeposition for efficient electroreduction of CO2 to formate
摘要
Abstract
Electrocatalytic CO2 reduction reaction(CO2RR)is regarded as an effective approach to reduce CO2 emissions and produce various high-value compounds.In this study,a Cu-Sn alloy catalyst with a wheat-ear-like dendritic structure was prepared via a simple one-step electrodeposition method and used for the selective electro-reducing CO2 to formate.Experimental results demonstrate that,compared to Cu and Sn electrodes,the Cu-Sn alloy catalyst exhibits higher catalytic activity and selectivity toward formate due to its unique wheat-ear-like structure,which could provide abundant active sites for the reaction process.The Faradaic efficiency for formate reaches up to 80％,and remains above 70％within the potential range from-1.7--2.0 V.Combined electrochemical data and XPS analysis revealed that Cu and Sn atoms collectively modulate the adsorption of the CO2*-intermediate during the electroreduction process.Therefore,this simple preparation method offers a new pathway for the design of bimetallic catalysts for CO2RR.关键词
