Abstract
The mosaic films made of TiO2 and hexagonal MoO3 nanoparticles not only demonstrate high activity in the reactions of photooxidation of the adsorbed organics in air conditions but also store the photoinduced charge as the result of MoO3 reduction by photoelectrons injected from titania which behaves as a photogenerating component. The charge accumulated via this light-driven reduction is spent under dark conditions in the reaction of molecular oxygen reduction yielding peroxide species. As the result, TiO2/h-MoO3 nanocomposite films retain oxidation ability for ca. 4 h after UV illumination. This photocatalytic material opens fresh avenues in fabrication of self-sterilizing coatings capable to generate reactive oxygen species not only under actinic illumination but also under dark conditions.
