Oxygen evolution reaction (OER) is an obstacle to the electrocatalytic water splitting due to its unique four‐proton‐and‐electron‐transfer reaction process. Many methods, such as engineering heterostructure and introducing oxygen vacancy, have been used to improve the catalytic performance of electr...
