Synthesis and Catalysis of Fe₃O₄ Nanoparticles for Degradation of Rhodamine B

Abstract:

Fe3O4 nanoparticles (Fe3O4 NPs) were successfully prepared via chemical co-precipitation method under the assistance of ultrasound irradiation and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). a series of experiments were carried out to investigate the degradation of Rhodamine B(RhB) by the obtained heterogeneous Fe3O4 catalysts in the presence of H2O2. The effects of catalyst loading,initial pH, reaction temperature, oxidant concentration were discussed. The result indicated that the optimal conditions were Fe3O4 NPs dosage 0.7 g/L, initial pH=3.0, reaction temperature 60°C, oxidant concentration 20 mmol /L.
