Abstract
TiO2 was used as the support for preparation of Pt/WC/TiO2 composite catalyst. The composites were characterized by XRD, SEM and TEM methods. The electrocatalytical activity of Pt/WC/TiO2 composite for oxidation of methanol was investigated by cyclic voltammetry. Pt/WC/TiO2 exhibited higher activity compared with that of Pt/TiO2 and Pt/WC composite catalysts. Based on this we discussed the effects of crystal phases of TiO2 on the electrocatalytical activity of Pt/WC/TiO2 composite catalyst.
