Preparation and Catalytic Activity Analysis of TiO2
Three kinds of TiO2 materials named Ti0, Ti0.5 and Ti1.0 were prepared via hydrothermal synthesis method using Tetrabutyl titanate (TNB) as the material and different amounts of Gemini Surfactant we prepared as the template. Then the prepared TiO2 nanoparticle was characterized by Scanning electron microscope(SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM). Taking the UV light as the light source ,the photocatalytic activity of TiO2 to rhB was studyed . The results showed that the degradation rate of Ti0, Ti0.5 ,Ti1.0 to RhB respectively was 93.6 % , 93.9 %, 99.7 % at the time of 3 hours. The catalytic activity of Ti0.5 and Ti1.0 was obviously better than Ti0, what’s more, Ti1.0 almost made RhB completely degradated at the time of 3 hours.
