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.
