Abstract： |
The preparation method of TiO2 film photocatalyst includes the following steps: firstly, using n-butyl titanate or titanium tetrachloride as precursor, adding pore-forming agent to prepare active layer sol, utilziing pulling-plating process to directly apply the active layer sol on the cleaned flexible base body, centrifugal removing excess sol, then placing the flexible base body with loaded gel into a water hot still, and using water-ethyl alcohol mixed solvent to form nano crystal TiO2 film photocatalyst at low temp. |
