Fabrication and photocatalytic activity of TiO2/MoO3 particulate films.
TiO(2) and TiO(2)/MoO(3) particulate films were successfully prepared using a Langmuir-Blodgett technique. The as-deposited films were characterized by X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and electron probe microanalysis (EPMA). The results indicate that the TiO(2) and TiO(2)/MoO(3) films are composed of separate layers of TiO(2) and MoO(3) particles. Furthermore, the photocatalytic activity of the films was evaluated from the decomposition of a stearic acid film under ultraviolet and visible light irradiation. It was found that photocatalytic activity is significantly enhanced by the layer structure of the TiO(2)/MoO(3) film, compared to the single layer TiO(2) film.
