| Abstract: | PtRu/C-TiO2 catalysts were prepared by hydrolysis of Ti(OBu)4 on commercial PtRu/C. The catalyst was characterized by XRD, TEM, and XPS. The electrochemical performance of catalysts was testified by cyclic voltammetry (CV) and chronoamperometry (CA) in 0.5 M C2H5OH + 0.5 M H2SO4 solution. The results showed that the added TiO2 can improve the electrocatalytic properties of the catalyst toward methanol oxidation. The mechanism for the effects of TiO2 on catalytic activity of PtRu/C to methanol oxidation is also discussed. |
