| Abstract: | TiO2 colloid was prepared by means of sol-gel method.TiO2 colloid was coated on the surface of glass,then dried and sintered,and nanometer TiO2 thin film was formed. The phase and structure of the film have been studied by XRD and SEM,and the absorbency of the film has been researched by UV-vis spectroscopy.The photocatalytic activities for the degradation of rhodamine B were investigated.The results indicated that the concentration,pH of TiO2 colloid and heat-treatment atmospheres have obvious effects on the photocatalytic degradation rate. |
