TiO2/glass films have been prepared by a sol-gel method withtitanium tetrabutoxide as precursor. XRD and XPS results indicate the film is composed of anatase phase and with TiO2 size of about 15～25 nm. Triboloyical study indicates the TiO2 film has a long antiwearing life. The TiO2/glass film shows a high catalytic activity in photodegradation of rhodamine B in aqueous solution. The photodegradation follows first order kinetics and its reaction rate can be expressed by Langmuir-Hinshewood equation.
