摘要

The oxygen reduction reactions (ORR) play a crucial role in the electrochemical energy storage devices,such as fuel cell,metal-air batteries [1-3].However,their larger scale applications are hindered by the sluggish slow kinetics of the ORR.Up to now,platinum (Pt)-based catalysts are still known as the best ORR electrocatalysts owing to the relatively low overpotential,high catalytic activity and current density [4].
