Prepared anatase phase TiO2 photocatalysts films on ITO and glass substrate by RF-magnetron sputtering, and the metal island coating with TiO2 film. In our research, we discuss (1)metal island (2)substrate (3)reaction position (4)reaction time and (5)light source effect of photocatalyst activity. Characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), field emission-scanning electron microscope (FE-SEM), UV-visible spectrometer and I-V curve. The experimental results indicate that In-TiO2/ITO film may growth such as silver polygon、branch、net and wire nanostructure. By XRD analysis results , the product by photoreduction is silver, and the mainly growth face is {111}.
