Formations and properties PHOTOCATALYTICally active thick films with dioxide titanium
Abstract
Photocatalytically active porous films as thick as 20 µm were fabricated from the paste composed of sodium silicate solute and nanodispersed TiO2 powder fired at 200 to 400°С on glass substrates. It was shown, that the porosity of films can be extended by chemical etching, that allows an increase of the effective surface up to 30 m2/g. The photocatalytic activity of the films was estimated by decomposition the organic dye which was aqueous solution of methylene blue subjected to ultraviolet radiation.
