Abstract: TiO₂ has been widely studied and applied in environment protection due to its excellent photocatalytic activity and physicochemical characteristics. Especially at the time when the pollution problem becomes more and more conspicuous, the study on TiO₂ catalyst has more practical significance. Film is an important application pattern of TiO₂ catalyst, which is more effective to utilize light and easier to be recycled compared with TiO₂ powder, and can be facilely deposited on a variety of substrates such as glass slide, porcelain bricks, metal panels, etc. Hence, the research status of the preparation of TiO₂ photocatalytic film was reviewed in this paper.

Key words: titania, film, preparation, photocatalysis
