Simple synthesis of
nanocrystalline titanium dioxide (TiO2) by impregnation method was
investigated. Titanium tetraisopropoxide (TTIP) was used as the precursor and starch as the
impregnations matrix. TiO2 nanoparticles of 100 nm in size were
synthesized by varying the conditions. Crystallization and the growth of the
particles were accelerated with increasing calcination temperature and time.
The X-ray diffraction study shows that the product has anatase crystal
structure at calcination temperatures below 600 oC. Anatase
phase and rutile phase coexisted at 700 oC. At temperatures
above 700 oC, the intensity of the anatase crystal phase peaks
decreased and a peak of the new rutile crystal phase appeared at 2θ of
27.42(110), 36.11(101), 41.28(111) and 55.06(220). In more than 800 oC
of temperature, rutile phase only existence.
