Abstract: The nickel-doped titanium powder and multilayer thin films for photocatalytic experiment were investigated. In order to improve the photocatalytic activity of TiO2 in the visible region, nickel-doped TiO2 powder was fabricated by Sol-Gel method. Moreover, we also studied the relationship between thin film surface conditions and photocatalytic activity. Based on experimental results, nickel-doped TiO2 powder absorbed slightly visible light, and multilayer thin films reduced cracks on the surface. Multilayer thin films made of commercial P25 TiO2 powder mixed with nickel-doped powder enabled the highest photocatalytic activity.
Key words: Electrophoresis deposition, multilayer thin film, Ni-doped TiO2 powder, photocatalyst.
