Abstract:

A layered porous Fe-N-codoped carbon material(Fe-N-CM) was synthesized by sacrificial template method using cheap natural product red date as exclusive carbon source, g-C3N4 as sacrificial template and nitrogen source. The morphology and structure of Fe-N-CM were characterized by XRD, XPS, TEM and BET. The oxygen reduction reaction(ORR) performance of the obtained catalyst was evaluated by rotating disk electrode(RDE). The results show that Fe particles well dispersed are Fe-N-CM with high surface area(429.8 m2/g) and synergistic effect of Fe and N exhibits high ORR activity. And the long-term stability and methanol resistance of Fe-N-CM for ORR are even superior to commercial Pt/C.

Key words: Sacrificial template method, Fe and N codoped carbon, Electrocatalysis, Oxygen reduction reaction
