摘  要:A new strategy to fabricate oxygen-promoted Cu,N co-doped carbon(OP-CuN@C)composites is reported.The strategy consists of only two simple steps:chemical polymerization and high temperature carbonization.Electrochemical measurements were conducted to investigate the catalytic activity and mechanism of ORR on the resulting samples.All the electrochemical results indicate that OP-CuN@C exhibits the best ORR catalytic activity.The ORR onset potential of OP-CuN@C is slightly lower than that of commercial Pt/C catalyst.The good performance is attributed to the large specific surface area,high content of heteroatoms(pyridinic,graphitic nitrogen,and oxygen atom)and synergistic effect between divalent copper and nitrogen dopant.
