Abstract:
Template synthesis of titania was conducted in solutions of polysaccharides, xanthan and sodium hyaluronan, prepared in ethylene glycol and on cellulose fibrils placed in ethylene glycol. The process was controlled by the addition of water in amounts sufficient only for the hydration of polysaccharides. When the precursor of TiO2, tetra(isopropyl) orthotitanate, was added, the fast reactions of hydrolysis and condensation were triggered only after its contact with water, which provided the precipitation of titania on xanthan and sodium hyaluronan macromolecules or on cellulose fibrils. The morphology of the synthesized TiO2 samples depended on the reagent concentrations in a reaction mixture. Amorphous titania was transformed by calcination into the crystalline state. Some of the obtained TiO2 samples have rather high photocatalytic activity comparable to that of the commercial photocatalysts.
