Abstract

In this study, in order to increase surface area of ZINC OXIDE as a catalyst, ZnO impregnated to Alumina-Silica matrix using simultaneous reaction of zinc nitrate, tetraethyl orthosilicate, ZINC OXIDE and aluminum nitrate by SOL-GEL METHOD. Values of 20, 30, 40, 50, 70 and 100 weight percents of ZINC OXIDE with an equal weight ratio of SiO2-Al2O3 were mixed to achieve the desired composite. The characterizations of nano-structural composites were investigated by X-ray diffraction, FESEM/ EDS and BET studies. The results showed that crystalline ZnO in Alumina-Silica matrix has been formed and dispersed in this matrix caused to reduction in growth of ZnO, prevention of agglomeration and increasing of area surface of composites. Performance of these composites with ZnO as a photocatalyst was evaluated in degradation and adsorption of methyl orange as a textile dyes model.
