摘要：

A carbon supported Pt-decorated PdFe alloy nano-core catalysts (Pt-PdFe/C) for methanol oxidation is prepared via metathetical reaction between PdFe alloy nanoparticles (deposited on carbon) and PtCl42- in aqueous solution. Morphology and composition of the synthesized catalyst are characterized by Transmission Electron Microscope and X-ray diffraction. Experimental results show the electrochemical active surface area of the Pt-PdFe/C catalyst is much larger than those of the PdFe/C and Pt/C catalysts. Furthermore, the mass specific peak current is 1.01 A mg(-1) for methanol oxidation on the Pt-PdFe/C electrode, an increase by a factor of 3.5 times and 12.6 times as compared to PtRu/C and Pt/C, respectively. The facile fabrication and high electrochemical performance of Pt-PdFe/C highlight its potential application as anode for DMFCs.
