The study of the preparation and properties of composite photocatalyst Ag-TiO2-SiO2
Abstract: we used silica microspheres prepared by classical stober (sol-gel) preparation methods  as nuclear, and prepared core-shell particles TiO2-SiO2 by sol-gel method with phthaly butyl acetate as raw materials,and doped silver by method of the silver-mirror .  We regarded methylene blue as the goal degradants, and studied its photocatalytic activity . The experimental results show that the catalytic activity of modified core-shell particles, Ag TiO2-SiO2 , improved obviously 2.5 times, we characterized by XRD, TEM and the results show that the composite particles doped with silver display excellent activity on some photocatalytic degradations of methylene blue .
Keywords: stober; Silica; Sol-gel; Silver dopping
