CO 2 Electroreduction In article number 2101424, Xuezhi Duan, Jin Wang, Jian Yang and co‐workers report an effective strategy to manipulate Cu surface oxidation states by polyvinyl pyrrolidone coverage on the surface of Cu nanoparticles. CO 2 electroreduction tests show that zero‐valent Cu atoms favor electrocatalytic CO 2 generation of CH 4 , and conversely, multi‐carbon products are obtained when zero‐ and monovalent valence states are mixed.
