Enhancing local K adsorption by high-density cube corners for efficient electroreduction of CO to C products.

Reducing carbon dioxide (CO) to high value-added chemicals using renewable electricity is a promising approach to reducing CO levels in the air and mitigating the greenhouse effect, which depends on high-efficiency electrocatalysts. Copper-based catalysts can be used for electroreduction of CO to produce C products with high added value, but suffer from poor stability and low selectivity. Herein, we propose a strategy to enhance the field effect by varying the cubic corner density on the surface of CuO microspheres for improving the electrocatalytic performance of CO reduction to C products.
