| Description |
Anatase nano-powder (TSP) was synthesized by annealing of peroxide-treated titanyl sulfate hydrate at 800°C. The product and intermediates (prepared at lower temperatures) were characterized by X-ray powder diffraction and IR spectroscopy. Their photocatalytic activity was studied in the model reaction of Methyl Orange degradation under UV irradiation. The properties of so-made samples were compared to the properties of the products of annealing naked titanyl sulfate hydrate under similar conditions (TS). Photocatalytic activity of the TSP samples is higher than photocatalytic activity of TS and commercial anatase Hombikat UV100, which is manufactured by pyrolysis of naked titanyl sulfate. |
