Abstract
Tiles functionalized with W-doped TiO2 film has been prepared and tested in the discoloration of aqueous solution of methylene blue (MB) used as model pollutants, in presence of UV light. The influence of tungsten and its loading on tiles surface were evaluated. Photocatalytic tests, performed at controlled temperature and atmospheric pressure, have shown that the increase in the tungsten loading strongly influences the photocatalytic activity; higher content of tungsten induces an increase of the discolouration rate. Moreover, the addition of tungsten modifies the structure of titania determining a remarkably photocatalytic activity.
