| Abstract: | Fe 3+-doped titanium dioxide films coated on silica(Fe 3+-TiO 2/SiO 2) were prepared by sol-gel method and characterized by means of SEM, Raman and DRS technologies. The activity of the prepared photocatalysts was investigated by the degradation reaction of Rhodamine B radiated with visible light(Xe lamp), and the results indicate that the presence of Fe 3+ ion in photocatalyst accelerates the degradation reaction rate of Rhodamine B. Moreover, the effects of the pH value and initial concentration of Rhodamine B in solution on the photocatalytic reaction were discussed. |
