The photo-assisted deposition (PAD) and impregnation (img) syntheses of nano-sized Pt 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 Pt-TiO2-SiO2 catalysts under visible-light condition for the oxidation of 2-propanol was evaluated. The results showed a notable photocatalytic activity of PAD-Pt-TiO2-SiO2 which was 1.5 and 4.7 times higher than that of imp-Pt-TiO2-SiO2 and TiO2-SiO2, respectively. Furthermore, PAD-Pt-TiO2-SiO2 catalysts exhibit a better catalytic property for hydrogenation of nitrobenzene, compared to the catalysts prepared by impregnation method.
