Surface| Резюме: | The photocatalytic properties of sol-gel derived Ti/Si films have been estimated by measuring the photodegradative oxidation of xantene dye - Rhodamine 6G under UV and visible light. Proton NMR and UV-VIS spectroscopic evidences are presented to demonstrate the route of dye phototransformation. The enhancement of the efficiency of mixed Ti/Si samples can be explained on the basis of increased surface area in comparison with that of commercial photocatalyst P-25 and preferential adsorption of the dyes on the silica part near the TiO2 nanoaggregates. |
