A template-free oxygen reduction reaction (ORR) catalyst Fe and N co-doped hierarchical porous graphitic carbon (Fe,N/PGC) was prepared by pyrolyzing a nontoxic and low-cost iron-coordinated polydopamine polymer precursor at 800 °C. The obtained catalyst manifests outstanding oxygen reduction activity in a wide range of pH.
