Heteroatom-doped porous carbon materials have recently attracted significant attention due to their superior catalytic activities for an oxygen reduction reaction (ORR). Transition metals co-doped with heteroatom are considered to have positive effects on improving ORR catalytic activity and stability. We report a series of novel Fe, Co incorporated in P-doped carbon materials, which give high ORR performance by an in-situ carbonization method. The ratios of the two metals and the carbonization temperatures are the key factors for the electrocatalytic activity. Due to the synergistic effect of the two transition metals, the Fe, Co incorporated in P-doped porous carbon sample, carbonized at 900 degrees C, shows the highest catalytic activity and stability. Electrochemical measurements show that Fe, Co incorporated in P-doped porous carbon materials are promising electrocatalysts to substitute Pt-based catalysts for fuel cells application.
