A Facile Plant Mediated Synthesis of Magnetite Nanoparticles Using Aqueous Leaf Extract of Ficus Hispida L. for Adsorption of Organic Dye

A facile and eco-friendly method for the synthesis of magnetite nanoparticles (Fe3O4 NPs) via CoPrecipitation in the presence of aqueous leaf extract of Ficus hispida L. The optical, crystalline, structural morphology and magnetic behaviour of the synthesized Fe3O4 NPs were characterized by Ultraviolet-Visible (UV-Vis), Fourier transform infrared (FTIR) spectroscopy, powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). The absorption spectrum reveals the peak at 379 nm, which confirm the formations of Fe3O4 NPs. XRD results reveals the formation of phase pure Fe3O4 NPs with cubic inverse spinel structure with crystallite sizes of 11.04 nm. The FESEM and TEM images clearly show that the spherical shape of Fe3O4 NPs with average particles size of 10.96 nm. Bright circular rings in the selected area electron diffraction (SAED) pattern showed good crystallinity. VSM results show super paramagnetic behaviour of Fe3O4 NPs. The synthesized Fe3O4 NPs have potential to adsorption of Methylene Blue(MB)
