TiO2 film is widely used in photocatalysis technology and has important application value in treating sewage, purifying air, utilizing solar energy, and self-cleaning. In this paper, the TiO2 film was prepared by sol–gel method using butyl silicate, anhydrous ethanol, and acetyl acetone. Sintering temperature is 380 and 530 °C. Microstructures are characterized by XRD and optical microscopy. The results show that the film sintered at 530 °C is a brookite, and the film sintered at 380 °C is anatase. The diffraction intensity increases as the number of layers increases. The surface of the TiO2 film prepared by the surface cover slide is flat and uniform.
