▎ 摘　　要

The performance of the oxygen reduction reaction (ORR) is a core issue in of fuel cells. ORR is a slow kinetic process; platinum normally is used to accelerate the reaction. This is a bottleneck for further development of fuel cells. Transition metal and heteroatom co-doped carbon materials have great potential in ORR catalysis. However, one-step synthesis of high activity and stability transition metal and heteroatom co-doped electrocatalysts is still a challenge. In this work, nitrogen, fluorine, and cobalt co-doped carbon catalyst, MPCo-950-5, is prepared from melamine, polytetrafluoroethylene, and cobalt acetate by a one-step method. MPCo-950-5 with a graphene-like structure and its specific surface area is 642 m(2) g(-1). The ORR half-wave potential of MPCo-950-5 is positively shifted by 35 mV compared to that of commercial Pt/C. In addition, MPCo-950-5 also shows excellent stability and methanol tolerance. This work serves as a simple and feasible method for preparing high ORR active transition metal and heteroatom co-doped carbon materials.
