Promotion effect of TiO2 on catalytic activity and stability of Pt catalyst for electrooxidation of methanol

► C and TiO2 are mixed up physically as the hybrid support of Pt. ► Methanol oxidation activity and stability on Pt/TiO2-C catalyst were improved. ► Pt and TiO2 interaction facilitates CO removal and hinders CO formation during methanol oxidation. ► The promotion effect should be attributed to the presence of TiO2.
