Abstract
Nowadays air and water pollutions are becoming a serious problem for urban environment. One of the efficient methods of purifying water and air is photocatalysis on TiO2 films. In this work, we obtained composite materials based on TiO2 and modified by Ag and SiO2 on the surface of the fiberglass material (Ag/SiO2/TiO2/FGM) by a sol-gel method. Complex studies were carried out to identify the phase compositions, morphology and textural characteristics of obtained samples by X-ray diffractometey, scanning electron microscopy, micro-X-ray spectral analyses and analysis of N2 adsorption-desorption isoterms. Surface area and average pore size of this sample is 8.2 m2/g and 11.4 nm respectively. Prepared composite Ag(0.5%)/SiO2(3%)/TiO2/FGM material revealed photocatalytic activity in model reaction of methyl orange azo dye photodegradation under UV-irradiation.
