英文摘要: Supported bimetallic PtFe catalyst is one of the most promising candidates for preferential CO oxidation (PROX) in H-2 for fuel cells. We are interested in developing novel PtFe catalysts which have special architectures and are more excellent in catalytic performance for the PROX reaction. In the present study, three kinds of novel alumina-supported PtFe, PtFe2 and PtFe3 alloy nanoparticles were prepared from Pt(acac)(2) and Fe(acac)(3) reduced by ethylene glycol in Ar atmosphere at 185 degrees C. The catalytic experiments showed that the three materials were more active for the PROX reaction under pretreatment both in He and H-2 atmospheres as compared to that of Pt/Al2O3 prepared by the same chemical route. Their structural property and iron state were investigated by X-ray diffraction and Fe-57 Mossbauer spectroscopy. The obtained results proved that the novel as-prepared PtFe/Al2O3, PtFe2/Al2O3 and PtFe3/Al2O3 materials are clearly different in the architecture and the oxidation state of iron as compared to the conventionally prepared one.
