The ethanol electrooxidation behaviors on Pt/MO2/CNTs(M=Sn, Ti, Ce)and Pt/CNTs catalysts in H2SO4 solutions were researched by cyclic voltammetry. It has revealed that the catalysts with the addition of metal oxides presented higher electrooxidation activity for ethanol, in particular, the Pt/CeO2/CNTs catalyst showed the best activity for ethanol electrooxidation intermediate. The Pt/SnO2/CNTs catalyst demonstrated the best ethanol electrooxidation activity when considering the synthetic effects of such parameters as the onset oxidation potential, peak current densities and total oxidation area.
