Transition metal and heteroatom codoped carbon materials have become the most promising materials to replace commercial platinum carbon (Pt / C) catalysts due to their low cost, high stability, and methanol resistance. In this work, iron‐nitrogen and phosphorus codoped carbon nanorod‐layer composites (N, P‐CNL) derived from phosphorus‐doped polyaniline (P‐PANI) by phytic acid (PA) and iron salt were successfully obtained after high‐temperature pyrolysis. As a result, the N, P‐CNL materials exhibited good electrocatalytic performance due to abundant active sites. The N, P‐CNL with 50% mass filling ratio of iron salt (named as N, P‐CNL‐1:1) displayed an enhanced limiting current density of −5.97 mA cm−2 at 1600 rpm and outstanding onset potential (−0.004 V) and oxygen reduction peak potential (−0.144 V). In general, this work can give insights into understanding the mechanism of codoped catalysts and synthesis the catalyst with excellent long‐term stability and resistance to methanol crossover and poisoning better than commercial Pt/C.
