Abstract The carbon−carbon coupling at the Cu/Cu 2 O Schottky interface has been widely recognized as a promising approach for electrocatalytic CO conversion into value-added alcohols. However, limited selectivity of C 2+ alcohols persists due to insufficient control over rectifying characteristics required precise bonding oxyhydrocarbons. Herein, we present an investigation manipulation coordination environment Cu sites through in-situ electrochemical reconstruction strategy, which indicates that construction low-coordinated facilitates enhanced interfaces, and induces asymmetric electronic perturbation faster electron exchange, thereby boosting C-C oxyhydrocarbons towards nucleophilic reaction process *H CCO-CO. Impressively, exhibit superior faradic efficiency 64.15 ± 1.92% energy ~39.32% production, while maintaining stability 50 h (faradic >50%, total current density = 200 mA cm −2 ) in flow-cell electrolyzer.
