| Abstract: | Carbon supported Pt-TiO2 catalysts were prepared by colloid method on different conditions. Electro-oxidation of methanol on Pt-TiO2/C catalysts of different methods is investigated by cyclic voltammetry （CV）, linear sweep voltammetry （LSV） and amperometric i-t curves techniques. It was found that the catalyst has the highest activity land stability to the oxidation of methanol. |
