Branched poly(ionic liquid)‑modifed magnetic nanoparticles as a nitrogen‑rich and hydrophilic support for stabilization of Pd nanoparticles and exploring its catalytic activity

Abstract

A novel magnetic nanocomposite modified with a new branched polymer containing nitrogen-rich ligand moieties was synthesized and used to stabilize Pd nanoparticles. The resulting catalyst was characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, vibrating sample magnetometry, thermogravimetric analysis and energy-dispersive X-ray. The synthesized catalyst has been applied as an efficient catalyst in the reduction of nitro compounds to corresponding amines and reductive degradation of organic dyes such as methyl orange and methyl red. The catalyst showed high stability and reusability for 10 runs without significant loss in catalytic activity.
