SYNTHESIS AND CHARACTERIZATION OF NANOPARTICLES OF FERROUS SULFIDE BY TWO DIFFERENT STARTING MATERIALS IN THE PRESENCE OF IONIC LIQUID-CAPPING AGENT

Room temperature ionic liquids (RTILs), a class of green and neoteric solvents, have attracted increasing interest over recent years as environmentally benign excellent alternatives to organic solvents in homogeneous and biphasic processes synthesis of several nanoparticles. A novel magnetically recoverable ionic liquid (1,1–Bis(3-Methylimidazolium-1-yl)methanechloride)-stabilized ferrous sulfide (FeS NPs) was fabricated by almost all the known a simple reduction method. Firm ferrous sulfide nanoparticles were prepared in good capitulate by reduction of ferric chloride using sodium borohydride by different reagents like thioacetamide (TAA) and sodium thiosulfate in the presence of ionic liquid such as 1,1-Bis(3-Methylimidazolium-1-yl) methane chloride. In the present investigation, FeS nanoparticles through different starting materials were synthesized and its characteristics were compared with each other. Structures were confirmed by elemental and spectral studies such as FT-IR spectroscopy, X-Ray Diffraction (XRD) analysis, Scanning Electron Microscope (SEM) analysis, Energy Dispersive X-ray spectroscopy (EDX), and Transmission Electron Microscopy (TEM) analysis.
