Supported titanium oxide as photocatalyst in water decontamination: State of the art

Over the last two decades the interest on systems based on supported titanium oxide as a photocatalyst for water decontamination has grown significantly. A variety of supporting materials, coating methods, and reactor arrangements have been investigated from engineering as well as from more fundamental points of view. A thorough search of the published reports of these investigations was carried out and they are analyzed in this paper. An overview of the state of the art in the subject is given.
