In this work, a low-cost and nitrogen-containing carbon material with mesopores and high surface area is synthesized by carbonizing carp with SiO2 nanoparticles as template. It is found that pyridinic-N dominates the N species on the surface of obtained carbon material, which can act as active sites for oxygen reduction reaction (ORR). The BET surface area of obtained carbon material is 401.7 m2 g...
