膦酸银配位聚合物电催化还原CO2的性能
Performance of silver-based phosphonate coordination polymers in CO2 reduction through electrocatalysis
摘要
Abstract
A silver phosphonate coordination polymer with a three-dimensional network structure,Ag10(H3L)2(H2O)2(4,4'-bipy),was synthesized by using a hydrothermal method and loaded onto carbon cloth to create a working electrode as a catalyst.The catalyst was characterized by using XRD,FTIR,and TG methods,and its electrocatalytic performance for CO2 reduction was investigated through cyclic voltammetry.The experimental results indicate that the catalyst embodies good crystallinity,phase purity,and thermal stability.It also demonstrates excellent catalytic activity and a high electrochemical active surface area in the electrochemical reduction of CO2,with the electrochemical active surface area reaching up to 1 014 μF/cm2.Under the condition of-1.0 V,the catalyst can maintain high electrocatalytic CO2 reduction stability,with the Faradic efficiency of CO production exceeding 90%after continuous operation for four hours.关键词
