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
observedinUV–visiblespectra.Thebandobservedat950cm�1 in FTIRanalysis
confirmedthepresenceofTi–O–Si bonds,theTEManalysisshowsboththeTiO2 and
TiO2–SiO2 wereinnanometersize.TheBET(Brunauer– Emmett–Teller)specificsurface
areas ofthesampleswere65and75m2/g forTiO2 and TiO2–SiO2 respectively.Thepower
conversionefficiency(PCE)ofthenanocompositeswerestudiedbyusingKeithely
electrometer andmultimeteranditwasfoundtobe2%and2.5%foreosin-Ysensitized
TiO2 andTiO2–SiO2 nanocompositesrespectively.
