Synthesis and Characterization of Iron Oxide Nanoparticles by Thermal Decomposition Method of Iron (III) Chelates

Magnetic iron oxide nanoparticles have numerous applications in the biomedical field. This paper reports the preparation and properties of iron oxide nanoparticles synthesised by thermal decomposition method from iron chelates. The iron oxide nanoparticles were characterized by FTIR, powder XRD, VSM, SEM and TEM techniques. FTIR and powder XRD studies show that iron oxide was formed as α - Fe2O3 in its pure form. VSM study shows that the particles have got ferromagnetic property. XRD, SEM and TEM images show that the particles formed are in nanometre crystallite size.
