Nanosized TiO 2 particles were prepared by solvothermal method using tetrabutyl titanate as precursor, ethanol and water as solvents, and a facile immobilization method of nanosized TiO 2 particles on woven glass fabric was developed. The samples obtained under various preparation conditions were characterized by means of thermo gravimetric analysis (TG) and differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution-transmission electron microscopy (HR-TEM), and Brunauer-Emmett-Teller (BET). The results show that the cube-shape of TiO 2 prepared by solvothermal method has good crystallinity of (101) surface, higher thermal stability and large specific surface area. Scanning electron microscopy (SEM) images confirmed that the immobilized TiO 2 film was uniformly distributed and clung to the substrate firmly. The photocatalytic activity of the catalysts was tested using photocatalytic oxidation of gaseous benzene. The results show that the TiO 2 calcined after solvothermal treatment suffers from lower specific surface area, and hence decreases its photocatalytic activity. The photocatalytic activities of the TiO 2 by solvothermal treatment with or without calcination in degradation 400 mg/m 3 benzene are 3.7 and 4.1 times as high as catalyst without solvothermal treatment, respectively.
