Preparation and photocatalytic properties of titanium(IV) oxide films

Abstract Films of titanium(IV) oxide were deposited on a variety of substrates by a simple nebulization and pyrolysis technique. Good uniformity and adhesion was obtained in all cases. The films showed appreciable photocatalytic activity toward the degradation of salicylic acid. The observed activity was increased by the deposition of elemental gold on the TiO 2 films.
