- Аннотация: Here, we study a performance of nanotubular Mg3Si2O5(OH)4/TiO2 hybrid adsorbent/photocatalyst in the process of decolorizing an aqueous solution of crystal violet. The composite material was produced by hydrothermal treatment with one or more subsequent cycles of TiCl4 treatment and vapor-phase hydrolysis according to the molecular layering technique. Decolorization was observed in situ by UV-VIS spectroscopy. It was found that TiO2 deposition yields 2 to 3 times improvement of decolorization performance. Depending on TiO2 phase type – amorphous or crystalline – this rise is related with either enhancement of adsorption rate either appearance of photocatalytic activity. Finally, fitting procedure issues in case of complex decolorization process were discussed.
