A two-step procedure was used for the preparation of the modified Ti/TiO2-Pt electrodes. The first step was anodisation of the titanium substrate to produce oxide film, and the second step was cathodic deposition Pt. The Ti/TiO2-Pt electrodes with nanocrystalline Pt films were obtained by galvanostatic deposit from H2PtCl4 and HCl solutions containing organic at 298 K~343 K. The mean grain sizes of Pt particles were 80 nm~130 nm. The surfaces of the as-prepared anodes before and after Pt coating were investigated by field emission scanning electron microscope scanning (FE-SEM) and X-ray diffraction (XRD). The parameters such as temperature and pH were discussed. The results show that the catalytic activity of n-TiO2 is remarkably improved by Pt doping and will increase further with prolonging of Pt deposition time.
