摘要
Abstract
Titania sol has been prepared by the sol-gel process with Ti(OC4H9)4 as precursor. TiO2 gel was obtained through hydrolysis and condensation process. Rare earth such as La2O3, CeO2 and Gd2O3 were introduced into the nanostructure TiO2. After TiO2 and rare earth doped TiO2powders were calcined at 400℃, 500℃, 600℃, 700℃ and 800℃ respectively, the characteristic analyses of the TiO2samples were studied by UV-VIS, XRD and TEM etc. It was found that there are some stronger absorption peaks at 200- 325 nm. The rare earth doping can increase the phase transition temperature converting anatase phase into ruttle phase, can decrease the grain size of TiO2particles and can improve the ant1-UV capacity of the coating fabrics.关键词
