AbstractOxygen evolution reaction (OER) and hydrogen evolution reaction (HER) play significant role on the practical applications of water splitting for producing clean fuel. Although some low‐cost metal oxides are active on catalyzing OER and HER, the instinct drawback of sluggish charges carriers transfer mobility decrease the reactions kinetic and hinder their application. To overcome the issue, CoV oxide is successfully built‐up with a CoOV structure to eliminate energy barrier during carriers transfer by the spin‐flip hopping process, which can be coated on various substrate to stimulate OER and HER. Moreover, the V “bridge” between CoO bonds stimulates the OER through more effective lattice oxygen oxidation mechanism, which can directly format OO bond in more effective pathway. The protocol could be spread on rational design of such OER electrocatalysts on various electrode to lower‐cost water splitting.
