Synthesis of Iron Oxide Nano Particles by the Use of Osmanthus Fragrance Leaf Extract

In this study, a one-pot eco-friendly synthesis technique was successfully employed in synthesizing iron oxide (Fe3O4) nanoparticles from FeCl3.6H2O and FeCl2.4H2O by the use of aqueous extract of sweet scented Osmanthus leaf. The synthesized nanoparticles were characterized by Scanning Electron Microscope (SEM), Fourier Transform Infrared, Thermogravimetry analysis (TGA), UV-vis spectrophotometer, X-ray diffraction (XRD) and Zetasizer nano 3600. The XRD analysis exhibited peaks at; 30.20o, 35.57o, 43.26o, 53.29o, 57.26o, 62.62o, 68.27o and 74.49o corresponding to 220, 331, 400, 422, 551, 440, 533 and 553 respectively which indicates the inverse spinel structure of Fe3O4 shows the crystalinity and high purity of our synthesized Fe3O4 nanoparticles. The iron oxide nanoparticles were in the size range of 20.25nm to 27.04nm.
