چکیده انگلیسی
An oxygen reduction reaction (ORR) catalyst comprising ultrafine iron oxide nanoparticles supported on N-doped Vulcan carbon (FeO1.4/N-C) was prepared via a two-step method. X-ray photoelectron spectroscopy revealed the iron oxide nanoparticles comprised Fe2O3 and FeO phases with a combined average oxidation state of 2.8. The FeO1.4/N-C catalyst produced an ORR onset potential of â0.056Â V and a half-wave potential of â0.190Â V in alkaline media, which was comparable to that of commercial Pt/C catalyst. Moreover, FeO1.4/N-C had higher methanol tolerance than Pt/C catalyst and thus affords a promising non-precious metal ORR catalyst for fuel cells.
