摘要:
A photocatalytic functional film has a structure of a substrate, a barrier layer and a photocatalytic layer stacked one on another. The barrier layer is an amorphous TiO 2 film, the photocatalyst layer comprises an amorphous TiO 2 film, and particles of visible light responsive photocatalytic material formed on the surface of the amorphous TiO 2 film. A method for producing a photocatalytic functional film includes: adding an alcohol solvent and an acid to a titanium precursor to obtain a TiO 2 amorphous sol by dehydration and de-alcoholization reaction; applying and drying the TiO 2 amorphous sol on a substrate to form a barrier layer; and applying and drying a composition formed by mixing particles of visible light responsive photocatalyst material with the TiO 2 amorphous sol on the barrier layer, to form a photocatalyst layer.
