| Abstract: | The anatase TiO2(A-TiO2) has the best catalytic activity in their three crystallographic forms.The Fe3+-doped TiO2 powders prepared via hydrothermal method is the anatase type,and the degradation of Rhodamine B photocatalyzed by as-prepared Fe3+-doped A-TiO2 was studied.The results of photocatalysis show that the best degradation rate of Rhodamine B is 81.69% under following conditions:adding 0.153 3 g as-prepared 5% Fe3+-doped(molar ratio) A-TiO2 powders into the 6 mg/L Rhodamine B acid solution(pH=2) illu... |
