摘要
Oxygen evolution reaction(OER)and oxygen reduction reaction(ORR)play critical roles in renewable electrochemical energy conversion and storage devices,such as regenerative fuel cells and metal-air batteries[1-4].Up to date,precious metal-based catalysts,e.g.Pt-based materials for ORR,IrO_(2)/RuO_(2)-based catalysts for OER[5-7],lead the way in speeding up the sluggish reaction kinetics due to their high catalytic activities.However,the large-scale commercialization of these catalysts has been seriously restricted by their scarcity and high cost.
