　　Bifunctional catalysts for oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)play the pivot role on the performance of rechargeable metal-air batteries.The hybrid materials of transition metal and carbon based materials are promising bifunctional catalysts,however,the mechanism of their enhanced catalytic activities remains elusive.
