Preparation of Anatase Fe~(3+)-Doped TiO_2 via Hydrothermal Method and Their Photocatalytic Degeneration of Methylgreen

Fe~(3+)-doped TiO_2 flims were prepared by the hydrothermal method with titanium sulfate as raw materials and were characterized by means of XRD and SEM,and the degeneration of methylgreen photocat-alyzed by as-prepared Fe~(3+) -doped TiO_2 was studied.Experiment results show that as-prepared TiO_2 crystals are anatase TiO_2(ie,A-TiO_2).The results of photocatalysis show that the best degeneration rate of methylgreen is 57%under follow optimum conditions:adding as-prepared 0.110 0 g 2%(molar ratio) Fe~(3+)-doped A-TiO_2 into the 16 mg/L methylgreen solution,then illuminated by vis,stirring quickly at room temperature for 8 h,and the best degeneration rate of methylgreen is 68%at the same condition but illuminated by UV(λ=254 nm).
