Efficient photocatalytic activity in the visible range has been achieved with titanium oxide thin films. Doping, induced by oxygen deficiencies, is the key to the increased photodegradation properties of the film as both experimental and theoretical studies of the thin films demonstrate. The Figure shows an AFM image of the surface morphology of a TiO2 layer.
