Sol-Gel Synthesis and characterization of nano iron oxide

We have utilized sol-gel method for producing nano structure of xerogel iron oxide with Ferric nitrate nonahydrate as precursor, ethanol as solvent and propylene oxide as gelation agent. Nano oxide at 70°C are produced and evaluated with SEM, TG/DTA, FTIR, and XRD.The results of these analysis confirm the existence of amorph iron oxide, water, γ-Fe2O3, α-Fe2O3, α-FeO(OH) and Fe(OH)3 in this mixture. The morphology of these particles shows that they are spherical and agglomerate because of high reactivity and high surface area.
