Abstract

A simple,lesstimeconsuming,costineffectivesol–gel methodwasusedtosynthesisTiO2
nanoparticles(TiO2) andTiO2–SiO2 nanocomposites(TiO2–SiO2) usingtitaniumtetra
isopropoxideasTiO2 and silicicacidasSiO2 precursors respectively.Thesynthesized
nanocompositeswerecharacterizedbyXRD,SEM,TEM,UV–visible,FTIRandBETanalysis.
The quantumconfinementeffectofTiO2 and TiO2–SiO2 wasconfirmedbyablueshift
