Oxygen reduction reaction (ORR) is an important process for the conversion and utilization of a wide range of renewable energy sources, and is critical for the shape of future energy scenario [1-10].However, ORR is a complex four-electron transfer process and is kinetically sluggish.It is urgent to develop high-efficient electrocatalysts to solve this problem [11-15].Up to now, precious metal-based catalysts such as Pt-based electrocatalysts have been widely studied and found to be one of the most efficient electrocatalysts for ORR.However, the high price and the small reserves limit their large-scale commercialization [10,16-23].Therefore, in order to fulfill needs for the practical applications, it is necessary to develop low-cost electrocatalysts, also with high activity and great stability [19,24-28].
