چکیده انگلیسی
In this work, we have developed a facile, low-cost and ecofriendly method for synthesis of nickel supported iron oxide magnetic nanoparticles (Ni/Fe3O4 MNPs) using Moringa oleifera (MO) leaves extract as reducing and capping agent. The as-synthesized Ni/Fe3O4 nanocomposite was characterized by various physicochemical characterization techniques such as FTIR, powder XRD, XPS, TEM and BET sorption methods. The results show that the Ni/Fe3O4 MNPs were exhibits spherical in shape with the size range of 16-20Â nm. The room temperature magnetic measurements of composite clearly evince ferromagnetic natures with saturation magnetization (Ms) of 76.8 emu/g. The catalytic activity of Ni/Fe3O4 MNPs towards degradation of Malachite green (MG) dye was determined by UV-vis spectroscopy. The results show that as-synthesized Ni/Fe3O4 MNPs is an efficient catalyst for the degradation of Malachite green as compared to previous reports.
