چکیده مقاله:
Amorphous metal oxides magnetic nanoparticles possess fascinating properties and a wide range of potential applications because of their unique structural and magnetic properties, nontoxicity, and high chemical stability. This work reports the preparation of amorphous Fe3O4 nanoparticles by ultrasound irradiation of a mixture of iron filings, Sodium hypochlorite, and PEG surfactant. The PEG surfactant acts as stabilizer and it is nontoxic, non- flammable and 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 catalytic activity in degradation of methylene blue.
