EFFECT OF INTRODUCTION SAS ON THE STRUCTURE OF THICK FILMS OF SILICATE GLASS AND NANOSTRUCTURED TiO2

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 substan...

Summary: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.
