The study of properties and catalytic activity of titanium dioxide doped with sulphure

Comparison was made by activity of TiO2 doped with sulphur (S-TiO2) and pure TiO2, synthesized by the sol-gel method, with TiO2 Degussa P-25 in course of photocatalytic oxidation by oxygen of the air of aqueous solutions of fulvic acids, humic and picric acids at two modes of radiation by a SVD-120 lamp (λ > 200 or λ > 320 nm). It is shown that at oxidation of fulvic acids and humic acid the activity of S-TiO2 is substantially higher than the activity of pure TiO2 under both modes of radiation, however, under conditions of the experiment the given samples were less effective at oxidation by picric acid.
