摘要
Oxygen evolution reaction(OER)is the imperative reaction for many energy storage and conversion devices such as recharge-able metal-air batteries and electrochemical water splitting[1].OER is a complex 4-electron process with sluggish kinetics and therefore requires electrocatalysts to overcome the high overpo-tential.Ruthenium oxide(RuO_(2))and iridium oxide(IrO_(2))catalysts can promote the OER process remarkably[2-4],however,their ex-tremely high cost,natural scarcity,and long-term instability con-strain their scale-up application in clean-energy technologies[5,6].It is crucial to develop inexpensive,highly efficient,and durable electrocatalysts for OER.
