Abstract

The Fe-doped ZrO2 powders were prepared by so-gel method.After that,Pt-Zr1-xFexO2/C catalysts were made by reducing platinum salts with ethylene glycol.The physical property of the catalyst was characterized by XRD and TEM.It was found that the distribution of the catalyst was narrow,the particle sizes of Pt and ZrO2 particles were 2~4 nm and 3~7 nm,respectively.The Cyclic Voltammetry and Chronoamperometry testing indicated that the electro-catalytic activity for methanol electro-oxidation on Pt-ZrO2/C catalyst increased when ZrO2 was doped with Fe.And Pt-Zr0.95Fe0.05O2/C catalyst showed the highest activity for the electro-oxidation of methanol.
