In order to improve the electrocatalytic activities of the Ti/TiO2 electrode, the nanotube TiO2 film was fabricated by anodic oxidation on TA1 samples, and then Ti/TiO2-Pt modified electrode was prepared through the deposition of Pt on the film. The compositions, crystal structures and surface morphologies before and after depositing were characterized with the aid of X-ray and FESEM. The results showed that Pt was deposited preferentially on the edge of the nanotube ostiums. The cyclic voltammetry and stationary current-potential curves indicated that the electrocatalytic activities of the Ti/TiO2 electrode of deposited Pt were improved evidently.
