【 摘 要 】

The influence of Fe2O3addition on the TiO2structure and photoactivity properties have been studied. The addition of Fe2O3on the TiO2done by TiO2-Fe2O3synthesized with variation of annealing temperature. The result showed that peak of anatase TiO2at 2θ = 25.35° and Fe2O3at 2θ = 54.20°. The XRD of TiO2show annealing temperature at 400°C is anatase phase and the composite with annealing at temperature 150°C, 300°C, 400°C and 500°C is crystalline anatase phase, due to the addition of Fe2O3. Photodegradation of Rhodamin B with TiO2at 400°C annealing temperature showed optimum degradation 36.2 %, and the composite with annealing at 400°C showed optimum degradation 44.3% for 300 minutes irradiation.
