Fe-N-doped porous carbon derived from petroleum asphalt (NPCA) was prepared via a facile template synthesis method, with urea as nitrogen source while Î±-Fe2O3 nanoparticles as template and Fe source. The as-prepared NPCA calcined at 900Â Â°C (NPCA-900) exhibits excellent electrocatalytic performance with high diffusion-limiting current density and stability comparable to those of commercial Pt/C catalysts in alkaline environment. The remarkable ORR performance of NPCA could be ascribed to the abundant porosity, large specific surface area (1060Â m2Â gâ1), as well as the doping of Fe-N (especially pyridinic N). The NPCA derived from cheap petroleum asphalt has good application future in the field of catalysis, while it may pave a new way to realize the clean and high value utilization of heavy oils.
