This paper presents an investigation over the photoefficiency of nanotubular titanium dioxide films in the degradation of organic pollutants: rhodamine B was chosen as model reactant. The effects of thermal treatments in several atmospheres on the oxides photoactivity are investigated. The degradation kinetics were examined as a function of the anodizing treatment duration and of the annealing atmosphere; either UV light or visible light were used to activate the photocatalyst, so as to detect the presence and the effect of doping elements in the oxide.
