Electrochemical CO reduction to C products over CuZn intermetallic catalysts synthesized by electrodeposition

Frontiers in Energy doi: 10.1007/s11708-023-0898-0

Abstract: Electrocatalytic CO2 reduction (ECR) offers an attractive approach to realizing carbon neutralityHerein, a one-step co-electrodeposition method was used to introduce Zn, a metal with weak *CO bindingIt was shown that, using an H-cell, the high Faradaic efficiency of C2+ hydrocarbons/alcohols*CO formed on Zn sites can move to Cu sites due to its weak binding with *CO, and thus enhance the C–Ccoupling on the Cu surface to form C2+ products.
