Abstract: Magnetic MnFe₂O₄ with functionalized graphene (MnFe₂O₄-G) was prepared by solvothermal treatment of inorganic salts with graphene oxide as a starting material. The as- prepared product was then characterized by using X-ray powder diffraction (XRD) and Field Emission Scanning electron microscopy (FE-SEM). FE-SEM observations show that manganous ferrite nanoparticles with sizes of 10-40 nm were well dispersed on graphene sheets. The obtained hybrid was further tested for its photocatalytic activity against malachite green (MG) dye degradation. Results show that the photocatalytic activity of as- prepared product (MnFe₂O₄-G) has about 67% of dye degradation. This research would provide a new easy separating platform for wastewater decontamination. The combination of the superior adsorption of graphene and the magnetic properties of MnFe₂O₄ nanoparticles can be used as a good adsorbent and separation tool to deal with water pollution.
