Abstract

The superiority of silver deposited titania particles over bare titania particles for the photocatalytic oxidation of selected organic compounds is explained: the presence of silver mainly enhances the photocatalytic oxidation of organic compounds that are predominantly oxidised by holes, while it has only an insignificant effect on those organic compounds that require hydroxyl radicals for their mineralisation.
