Abstract

Abstract: The impregnation method was applied to prepare the platinum – ruthenium (Pt-Ru) catalysts in which the content of Pt was 15%, and the atomic ratio of Pt and Ru was 2:1. The properties of the catalysts prepared with varied impregnated mediums (acetic acid, sodium acetate and water) and different carriers (carbon nanotubes and carbon aerogels) were studied in detail. The X-ray diffractometry(XRD) and transmission electron midroscopy(TEM) were used to observe the surface morphology of above Pt-Ru catalysts. The Energy Dispersive X-ray Spectrum(EDS) was used to analyze the composition of catalysts. The electrochemical performance of the catalysts was examined by cyclic voltammetry with a glassy carbon working electrode in a solution of 1.0 mol/L CH3OH and 0.5 mol/L H2SO4. In above all catalysts, the catalyst prepared with the metal precursor impregnated in CH3COOH and carbon aerogels as a carrier has the highest electrocatalytic activity. The peak current density gets to 38.24 mA/cm2, which is much higher than the rest of the catalysts prepared with other conditions in this paper.
