A highly resourceful magnetically separable magnetic nanoparticles from aqueous peel extract of Bottle gourds for organic dyes degradation

Abstract

Present work, described the green synthesis of Pd supported Fe3O4 magnetic nanoparticles BG/Pd/Fe3O4MNPs from aqueous Peel extract of Bottlegourds (BG) which act as reducing and capping agent. Synthesized nanoparticles of BG/Pd/Fe3O4MNPs was characterized by various techniques: Fourier transform infrared (FT-IR), powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy(XPS), transmission electron microscope (TEM), X-ray energy dispersive spectroscopy (EDX), Brunauer-Emmett-Teller (BET) method and vibrating sample magnetometer (VSM). The structure of synthesized BG/Pd/Fe3O4MNPs was face centered cubic structure confirmed by the X-ray diffraction analysis. Moreover, the synthesized BG/Pd/Fe3O4MNPs clearly reveals that they are well dispersed with uniform size (50nm) and displays high surface area of 27.6m2/g which is calculated by BET adsorption-desorption method. The magnetic behavior of BG/Pd/Fe3O4MNPs shows enhanced magnetic properties of saturation magnetization (Ms, ~15.9emu/g), by vibrating sample magnetometer (VSM). Furthermore, the catalytic activity of synthesized BG/Pd/Fe3O4MNPs in the reduction of methylene blue (MB) dye was explored by UV–Vis absorption spectroscopy. The synthesized BG/Pd/Fe3O4MNPs showed good catalytic activity in the reduction of MB dye which is confirmed by the results obtained form UV–Vis absorption spectroscopy. The results were discuss in term of molecular interaction between synthesized BG/Pd/Fe3O4MNPs and methylene blue (MB) dye.
