英文摘要	Ordered mesoporous nitrogen doped carbon supported iron oxide was prepared, which effectively reduced the overpotential of oxygen reduction. The physicochemical properties of the as-prepared catalysts were characterized by scanning electron microscopy, transmission electron microscopy, nitrogen adsorption-desorption test, powder X-ray diffraction, X-ray photoelectron spectroscopy and Raman spectroscopy. In addition, the activity and selectivity for oxygen reduction reaction was tested by rotating disc electrode wider alkaline conditions. The results show that iron was loaded in ordered mesoporous nitrogen doped carbon in the form of Fe2O3 after nitrogen pyrolysis, and its specific surface area reached 755 cm(2).g(-1). The results of Raman and X-ray photoelectron spectroscopy show that the graphitization degree of the catalyst increased with adding iron precursor. The impedance was decreased and its conductivity was increased. Under alkaline conditions, Fe2O3@NC exhibited a 4-electron oxygen reduction reaction, and its initial potential (-0.01 V vs Ag/AgCl) arid half slope potential (-0.13 V vs Ag/AgCl) were comparable to those of commercial 20% Pt/C. In addition, the catalyst had superior methanol resistance and excellent constant voltage stability compared with commercial Pt/C. The discharge power of Fe2O3@NC reached 88 mW.cm(-2), which was 1.29 times that of commercial Pt/C.
