摘要：

The photo-assisted deposition (PAD) and impregnation (img) synthesis of nano-sized Ag metal on TiO2-SiO2 are reported. The prepared catalysts were characterized by different techniques such as XRD, XAFS, TEM and nitrogen adsorption analysis Photocatalytic reactivity using Ag-TiO2-SiO2 catalysts under visible-light condition on the oxidation of EDTA with O-2 reaction was evaluated. The results have shown notable photocatalytic activity of PAD-Ag-TiO2-SiO2 which was 2 and 5 times higher than that of imp-Ag-TiO2-SiO2 and TiO2-SiO2, respectively.
