Ionic Liquid and Glucosamine Modified Magnetic Nanoparticles for Stabilization of Nano sized Palladium and Study of its Catalytic Activity

Abstract A magnetic nanocomposite comprising imidazolium ionic liquid and glucosamine is successfully synthesized and used for stabilization of Pd nanoparticles. This new material, Fe3O4@SiO2@IL/GA-Pd, is characterized by scanning electron microscopy (SEM), transition electron microscopy (TEM), X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FT-IR), elemental maps, energy dispersive X-Ray analysis (EDX) and vibrating-sample magnetometer (VSM). Prepared nanocomposite is applied as a catalyst in reduction of nitroaromatic compounds to desired amines at room temperature as well as in reductive degradation of organic dyes such as methylene Blue (MB), methyl orange (MO) and rhodamine B (RhB). Results show that the catalyst has excellent catalytic activity in the already mentioned reactions and easily recycled and reused for 11 consecutive cycle without its changing catalytic activity. TEM, XRD and VSM are confirmed the stability of the reused catalyst.
