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 TiO2 film, the photocatalyst layer comprises an amorphous TiO2 film, and particles of visible light responsive photocatalytic material formed on the surface of the amorphous TiO2 film. A method for producing a photocatalytic functional film includes: adding an alcohol solvent and an acid to a titanium precursor to obtain a TiO2 amorphous sol by dehydration and de-alcoholization reaction; applying and drying the TiO2 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 TiO2 amorphous sol on the barrier layer, to form a photocatalyst layer.

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 a SiO2 film, the photocatalyst layer comprises an amorphous TiO2 film, and particles of visible light responsive photocatalytic material formed on the surface of the amorphous TiO2 film. A method for producing a photocatalytic functional film includes: adding an alcohol solvent and an acid to a silicate precursor to obtain a SiO2 sol by dehydration and de-alcoholization reaction; applying and drying the SiO2 sol on a substrate to form a barrier layer; adding an alcohol solvent and an acid to a titanium precursor to obtain a TiO2 amorphous sol by dehydration and de-alcoholization reaction; and applying and drying a composition formed by mixing particles of visible light responsive photocatalyst material with the TiO2 amorphous sol on the barrier layer, to form a photocatalyst layer.
