Abstract
<p>TiO<sub>2</sub> thin films on borosilicate glass and quartz glass substrates were prepared in order to investigate the influence of the substrate on photocatalytic activity. The preparation of TiO<sub>2</sub> thin film was performed by sol-gel method. The influence of the substrate on TiO<sub>2</sub> crystallization was examined at different TiO<sub>2</sub> thin film sintering temperatures. The TiO<sub>2</sub> thin film was irradiated with black-light fluorescent lamps. Photocatalytic activity was compared using trichloroethylene (TCE). The photocatalytic activity of the TiO<sub>2</sub> thin film was confirmed to vary with the substrate. The crystal structures of the TiO<sub>2</sub> thin films prepared on the glass substrates were examined using X-ray diffraction analysis, and the UV absorption of the thin film was measured by means of a spectrophotometer.</p>
