ABSTRACTTitanium oxide and titanates based on Ba, Sr and Ca were prepared from commercial solutions of TiCl4 and HNO3. The main preparation steps for the sols consisted of elimination of chloride anions by distillation with nitric acid and addition of metal hydroxides for the titanates. Resulting sols were gelled and used to (1) prepare irregularly shaped powders by evaporation; (2) produce by a dipping technique thin films on glass, Ag, or Ti substrates; and (3) produce spherical powders (diameters <100 μm) by solvent extraction. Results of thermal and X-ray-diffraction analyses indicated that the temperatures required to form the various compounds were lower than those necessary to form the compounds by conventional solid-state reactions and comparable to those required with use of organometallic based sol-gel methods. Temperatures of formation could be further reduced by addition of ascorbic acid to the sols.

The photocatalytic activity of TiO2–SiO2 coated and TiO2 coated on 100% cotton and PES/Co fabrics was investigated through the self–cleaning of red wine stains and coffee stains. It was shown that a TiO2 species could be produced at temperatures of 25 °C, 40 °C and 60 °C with acceptable photo–activity and TiO2–SiO2 nanocomposites were prepared by a sol–gel process at a low temperature. The discoloration of red wine and coffee led to CO2 evolution that was more efficient for TiO2–SiO2 coated cotton for samples than of TiO2 coated ones. The textile surface did not show any change after several consecutive light–induced discoloration cycles of a red wine stain and coffee stain. The structural properties of these nanocomposites were characterized with scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT–IR). The scanning electron microscope (SEM) photo showed that the TiO2–SiO2 layer is thicker than TiO2 layer on the cotton fabric and PES/Co fabric and the Ti–particles were always surrounded by amorphous SiO2 and never alone by themselves. The TiO2–SiO2 nanocomposites were coated onto cotton and PES/Co fabrics by a simple dip–pad–dry–cure process.
