摘 要：Transparent anatase TiO2 nanometer thin films with photocatalytic activity were prepared via the sol-gel method on soda-lime glass. The thickness , crystalline phase, grain size, surface hydroxyl amount and so on were characterized by scanning electron microscopy （SEM） , X-ray diffraction （XRD）, transmission electron microscopy （ TEM）, X-ray photoelectron spectroscopy （XPS） and UV-visible spectrophotometer （ UV-VIS）. The photocatalytic activity of TiO2 thin films was evaluated for the photocatalytic decolorization of aqueous methyl orange . The effects of film thickness on the crystalline phase, grain size, transmittance and photocatalytic activity of nanometer Ti02 thin films were discussed.
