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 p...
