In article number 1901396, Shanqing Zhang, Jian Chen, Yexiang Tong, and co‐workers report a highly selective Cu 2 O/CuO heterostructure electrocatalyst for CO 2 electroreduction, which exhibits high faradic efficiency (95% for CO). The hybridization of Cu 2 O/CuO nanowires and Ni nanoparticles improves the adsorption of COOH* intermediates to promote the CO conversion efficiency. In situ Raman spectroscopic studies further confirm the existence of COOH* species and the engineered intermediate adsorption.
