Abstract

Ag and Au nanoparticles were found to significantly enhance the photocatalytic activity of self-organized TiO$_2$ nanotubular structures. The catalyst systems are demonstrated to be highly efficient for the UV-light induced photocatalytic decomposition of a model organic pollutant -- Acid Orange 7. The metallic nanoparticles with a diameter of ~10~$±$~2~nm (Ag) and ~28~$±$~3~nm (Au) were attached to a nanotubular TiO$_2$ layer that consists of individual tubes of ~100~nm of diameter, ~2~\textgreekmm in length and approx. 15~nm of wall thickness. Both metal particle catalyst systems enhance the photocatalytic decomposition significantly more on the nanotubes support than placed on a compact TiO$_2$ surface.
