The catalytic activity of nanotubular titanium dioxide flms formed during the oxidation of acetone
to carbon dioxide under the action of visible light with a wavelength of 450nm was found to be
approximately 2 times higher compared to standard titanium dioxide (Degussa P25). The nanotubular
flms were grown by the anodization of titanium foil using an original technique. Difuse refectance
spectra of the flms are attributed to enhanced activity in the visible spectrum by the nonstoichiometry
of titanium dioxide near the interface between the nanotubular flm and the titanium foil substrate.
