Photocatalytic Activity of Ag⁺-Doped TiO₂ Thin Films Prepared by Sol-Gel Method

Abstract:

TiO₂ and Ag⁺-doped TiO₂ thin films were successfully obtained on microscope glass slides by means of sol-gel method. Then the photocatalytic activity of the TiO₂ and Ag⁺-doped TiO₂ thin films was evaluated by the degradation of rhodamine B dye solution. The effects of both annealing temperatures and Ag⁺ contents on the photocatalytic activity of TiO₂ thin films were examined. The results indicated that the TiO₂ thin films with an atomic ratio of Ti:Ag=10:1 annealed at 300°C had a higher photocatalytic activity.
