Abstract
We have demonstrated in this work that single phase of alpha-Fe2O3
nanoparticle can be prepared using gelatin. it was characterized by
X-ray powder diffraction (XRPD) technique, gas sorption technique (BET),
thermogravimetric analysis (TGA) and transmission electron microscopy
(TEM). The nanoparticle was obtained from an aqueous solution of gelatin
and FeCl3 center dot 6H(2)O, as Fe source, annealed in the temperature
range of 200-600 degrees C for 12 h. The mean particle size of this
powder measured with XRPD is about 100 nm and this size agrees well with
TEM experiments. Also, the TEM result shows agglomeration that was
confirmed by BET technique. These results show that gelatin could be an
alternative organic precursor to produce metal oxide powders with
nanometer dimensions. (C) 2007 Elsevier B.V. All rights reserved.
