Photocatalytic activity of TiO2 nanofilms deposited onto polyvinyl chloride and glass substrates

Using Successive-Ionic-Layer-Adsorption-and-Reaction deposition technique, TiO2 films on polyvinyl chloride (PVC) and glass substrates were prepared. The photocatalytic and antibacterial activities of TiO2 films on PVC were evaluated by monitoring the photo-decomposition of 2-(phosphonomethylamino)acetic acid and Micrococcus lutes (odor causing bacteria). Photocatalytic degradation of methylene blue under UV source over as-made, hydrothermal and furnace annealed TiO2 films, and commercial TiO2 pellets were examined.
