CuO/Cu4O3@C复合材料在电催化还原CO2中的性能研究
Performance Study of CuO/Cu4O3@C Composites in Electrocatalytic Reduction of CO2
摘要
Abstract
[Purposes]Electrochemical CO2 reduction reaction(CO2RR)to high-value chemicals is currently receiving widespread attention.In order to improve the electrocatalytic activity and selec-tivity,it is necessary to prepare catalysts with superior CO2RR properties.[Methods]In this study,wheat bran-based biochar(C)was prepared and coupled with copper oxide to get composite electro-catalysts through a simple hydrothermal method,and physicochemical characterizations and electro-chemical performance testings were further condueted.[Findings]The results suggest that the CuO/Cu4O3@C-2 shows the best Faradaic efficiency of C2H4(46.32%)at-1.08 V(vs.RHE).Meanwhile,the sample displays excellent stability for 11.5 h at-1.08 V(vs.RHE).[Conclusions]This study pro-vides a feasible strategy for the synthesis of cost-effective catalysts with high electrochemical perfor-mance.关键词
