Effects of Preparing Conditions on the Performances of Nano La(S,C)-TiO2 Films
The La (S,C)-TiO2 oriented films with honeycomb ceramic wafers as carriers were prepared by template hydrothermal synthesis. The effects of the hydrothermal reaction temperature and the amount of template agents on the performances of nano-TiO2 films were studied. The films were characterized on the XRD, BET, EDS and SEM. The results showed that the TiO2 films with anatase phase were obtained when hydrothermal reaction temperature was 150 °C and the reaction time was 10h, and the oriented films were obtained when the molar ratio of PEO-PPO-PEO（P-123）to Ti was 0.03. The data also revealed that the specific surface area of particles in the film increased from 148 m2/g to 240 m2/g, and the oriented film could fully decompose methyl orange in water for 3 h.
