A Novel Sonochemical Method for the Synthesis of Amorphous Iron Oxide Nanoparticles and Its Photocatalytic Application

Amorphous metal oxides magnetic nanoparticles possess fascinating properties and a wide range ofpotential applications because of their unique structural and magnetic properties, nontoxicity, and high chemicalstability. This work reports the preparation of amorphous Fe3O4 nanoparticles by ultrasound irradiation of a mixture ofiron filings, Sodium hypochlorite, and PEG surfactant. The PEG surfactant acts as stabilizer and it is nontoxic, nonflammableand easy to handle. The structure and morphology of particles are analyzed by X- Ray Diffraction (XRD),FT-IR and UV-Vis spectra, SEM and TEM microscopy. The Amorphous Fe3O4 nanoparticles show good catalyticactivity in degradation of methylene blue.
