EFFECT OF INTRODUCTION SAS ON THE STRUCTURE OF THICK FILMS OF SILICATE GLASS AND NANOSTRUCTURED TiO<sub>2</sub>
Abstract
Photocatalytically active porous films as thick as 20 µm were fabricated from the paste composed of sodium silicate solute and nanodispersed TiO2 powder and SAS fired at 200 °С on glass substrates. It was shown, that the porosity of films can be extended by the introduction of surface-active substance. The photocatalytic activity of the films was estimated by decomposition the organic dye which was aqueous solution of methylene blue subjected to ultraviolet radiation.
