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