Abstract:Ag-doped TiO2/SiO2 with visible light response was prepared by a simple sol-gel method using titanium w-butoxide (TNB), tetraethoxysilane (TEOS) as precursors, and silver nitrate (AgNO3). The synthesized Ag-TiO2/SiO2 were characterized by SEM, XRD, PL (photoluminescence) emission and UV-Vis absorption spectroscopy. Their photocatalytic activities were evaluated by treating aqueous solutions of phenol under simulated visible light illumination. The role of silver doped was investigated in the range 1% – 5% (mol… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
