Photocatalytic Activities of Fe3+-Doped TiO2 Thin Films Prepared by Sol-Gel Method
TiO2 and different contents Fe3+-doped TiO2 thin films were successfully obtained on microscope glass slides by Sol-Gel method. Then the photocatalytic activities of the samples were evaluated by the degradation of Rhodamine B dye solution. The effects of both annealing temperatures and Fe3+ contents on the photocatalytic activities of TiO2 thin films were examined. The results indicated that the sample with an atomic ratio of Ti:Fe=7:3 annealed at 500°C had a higher photocatalytic activity.
