Abstract

Nanometric composite TiO2, TiO2-SiO2 (TS10) and Ag-TiO2-SiO2 (A4TS10) powder photo-catalysts have been synthesized via sol-gel assisted with hydrothermal treatment method and employed for aqueous phenol decomposition under sunlight irradiation. Characteristics of those samples are analyzed by using X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR), Energy dispersive X-ray (EDX), Transmission electron microscope (TEM), Brunauer-Emmett-Teller (BET) surface area and UV-Vis absorption method. The results of characteristic analysis show that all synthesized samples have the size of spherical nanostructures with the average nanoparticles size in range of 20 - 30 nm and pure anatase phase at a high crystalline degree Moreover, the phenol degradation of TiO2, TS10, A4TS10 samples increases significantly after 3h irradiation from 59%, to 68%, and 82%, respectively. These results demonstrate that Ag-TiO2-SiO2 is a promising candidate material for the wastewater treatment application in the future..
