SINTESIS DAN KARAKTERISASI NANOKRISTAL TiO2-SiO2/KITOSAN: EFEK TEMPERATUR KALSINASI DAN SURFAKTAN CTABr
Abstract: TiO2-SiO2/chitosancompoundhas been
syntesized by using
sol-gel method. The
aim of this research
is to carry
out some synthesis
modification to get
TiO2-SiO2/chitosan.
Variation of calcinations
temperature of 400 and 500oCwere examined to optimaze the reaction. Some result
of characterization have
indicated that the
morphology of compound
changed during the proces. XRD pattern showed that the
highest intensity found in the composite is anatase. It was also found that the
crystalinity TiO2-SiO2influenced by CTABr and chitosan. Scanning Electron Microscopy (SEM)
images showed that
the particle of
composite homogenously distributed with pored surface. Fourier
Transform Infrared (FTIR) spectrum showed that there are Ti-O-Si , Ti-O-Ti, and
Si-O-Si interaction investigated around 4000-400 cm-1.
