Abstract

Abstract The carbon−carbon coupling at the Cu/Cu 2 O Schottky interface has been widely recognized as a promising approach for electrocatalytic CO 2 conversion into value-added alcohols. However, the limited selectivity of C 2+ alcohols persists due to the insufficient control over rectifying interface characteristics required for precise bonding of oxyhydrocarbons. Herein, we present an investigation into the manipulation of the coordination environment of Cu sites through an in-situ electrochemical reconstruction strategy, which indicates that the construction of low-coordinated Cu sites at the Cu/Cu 2 O interface facilitates the enhanced rectifying interfaces, and induces asymmetric electronic perturbation…
