Iron Oxide Nanoparticles: Synthesis, Characterization and Applications (original) (raw)

Iron oxide is a mineral compound which occurs in different forms like hematite, magnetite and maghemite. Fe-based nanoparticles act as new generation environmental remediation technologies, and provide cost-effective solutions to the most demanding environmental cleanup problems. The synthesis of magnetic iron oxide nanoparticles (IONPs) has been intensively developed not only for its fundamental scientific interest but also for its many technological applications, such as targeted drug delivery, magnetic resonance imaging (MRI), gas sensing, photocatalytic degradation of organic pollutant, etc. In this review, different methods like sol-gel, co-precipitation, micro-emulsion, thermal decomposition to prepare iron oxide nanoparticles have been described. Characterization of iron oxide nanoparticles is done by scanning electron microscopy(SEM), Transmission electron microscopy(TEM), X-ray powder diffraction(XRD), and Fourier transform infrared spectroscopy(FT-IR). Also various applica...
