•Pyrolysis of covalent organic frameworks (COFs) for construction of M/N/C ORR electrocatalysts.•Excellent electrocatalytic activity toward ORR, which is quite comparable to that of the commercial Pt/C.•A possible insight into the ORR at the M/N/C catalysts.
A novel efficient electrocatalyst for oxygen reduction reaction (ORR) was synthesized by pyrolysis of a cobalt-based covalent organic framework, which shows electrocatalytic performance comparable with the commercial Pt/C for ORR via an almost four-electron pathway in alkaline media without methanol-crossover effect. This work not only provides a possible insight into the ORR at the M/N/C catalysts, but also paves a new route to the development of novel precious metal-free ORR electrocatalysts with high activities for ORR.
