WO₃/TiO₂ Nanotubes with Strongly Enhanced Photocatalytic Activity

Abstract

Mixed oxide photocatalysts: WO3- containing TiO2 nanotubes were prepared by self-organizing electrochemical anodization of TiW alloys (Ti 0.2 W see figure, and Ti 9 W). It is shown that a content of only 0.2 at % WO3 with respect to the titania nanotubes leads to a very significant increase of the photocatalytic reaction rate compared not only to pure anatase TiO2 nanotubes, but also in comparison with any other modified TiO2 nanotube system reported up to now.
