Photocatalytic Activities of Anatase Nanoparticles Thin Film Coatings

Anatase sol was synthesized by hydrolysis and condensation of titanium-n-butoxide in acidic aqueous condition. It was deposited on soda lime glass by spin coating method in room temperature. Characterization of sol and coatings were investigated. Results are demonstrated the mean particle size of the sol was in the range of 30-40 nm and did not change in the coating. In addition, the particle size distribution is uniform in the coating surface. Crystalline structure of deposited film is also investigated. Photocatalytic activities of films were studied by degradation of a colour indicator under different UV exposition time.
