Cerium modified Pt nanoparticles catalysts have been prepared using Ce(III)-ethylenediamine-tetraacetic acid (EDTA) chemistry with an impregnation method of 30%Pt/Carbon Vulcan XC-72. EDTA was used as a chelating agent to form a Ce(III) complex to achieve good dispersion of ceria on Pt/C while maintaining +3 oxidation state. Different compositions of Ce(III) with Pt/C have been examined to optimize the catalyst material. The methanol and ethanol oxidation studies were performed using the GC electrode previously modified with Vulcan-Pt and Vulcan-Pt-Ce(III). The catalytic activity toward methanol and ethanol oxidation for the different electrodes was performed using cyclic voltammetry (CV), linear sweep voltammetry (LSV) and chronoamperometry with a 1.0 M CH₃OH solution in 0.5 M H₂SO₄ and, for ethanol, a 1.0 M C₂H₅OH solution in 0.5 M H₂SO₄. The catalyst samples were characterized by using the characterization technique of X-ray diffraction. It has been found that the catalytic activity of Ce(III)/30wt%Pt/C exhibited better activities than 30wt%Pt/C in direct methanol fuel cell and direct ethanol fuel cell. A Vulcan-Pt-Ce(III) doped catalyst was prepared by a simple and cheap impregnation method using EDTA as chelating agent. The preparation method will allow the mass production of the material catalysts without additional significant cost.
