Titanium dioxide thin films have been prepared from
tetrabutyl-orthotitanate solution and methanol as a solvent by sol-gel dip coating technique. The
thermal properties of TiO2 gel were analyzed by thermogravimetry and differential thermal
analysis (TG-DTA). Structural properties of TiO2 thin films at different heat treatment
temperatures were analyzed by X-ray diffraction (XRD), Infrared Raman spectroscopy and scanning
electron microscopy (SEM). The results show that the TiO2 thin films crystallize in anatase phase
at 400 degrees C and the crystallinity of anatase phase was improved with increasing temperature.
The TiO2 thin films crystallize into the anatase-rutile phase at 600 degrees C and further into
the rutile phase at 800 degrees C. The photocatalytic performance of TiO2 film was tested for the
degradation of 2x10(-5) mol/L Rhodamine B. The degradation of Rhodamine B solutions reached
0.9x10(-5) mol/L after irradiated for 8 h under UV light. The TiO2 thin film exhibited relatively
high photocatalytic activity towards degrading Rhodamine B.
