Stabilizing Cu 0 –Cu + sites by Pb-doping for highly efficient CO 2 electroreduction to C 2 products

A Pb-doped Cu 2 O electrocatalyst is designed for highly efficient CO 2 reduction to C 2 products, which shows a C 2+ FE of 83.9%. Pb can stabilize Cu + and reduce the reaction energy barrier, thereby improving the catalytic performance.
