Design of Ag/ and Pt/TiO-SiO nanomaterials for the photocatalytic degradation of phenol under solar irradiation.

The design of hybrid mesoporous TiO-SiO (TS1) materials decorated with Ag and Pt nanoparticles was performed. The photocatalytic degradation of phenol under artificial solar irradiation was studied and the activity and selectivity of the intermediate products were verified. TiO-SiO was prepared by sol-gel method while Ag- and Pt-based photocatalysts (TS1-Ag and TS1-Pt) were prepared by photodeposition of the noble metals on TS1.
