Abstract
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−1 and the pore size is ca. 11.1 nm. Due to its high pyridinic-N content and mesoporous architecture, the ORR activity of obtained carbon material in alkaline media is comparable to that of commercial Pt/C catalyst. In addition, it shows a higher methanol tolerance than Pt/C catalyst, making it a potential alternative to Pt-based catalysts.
