Ionic-Liquid-Assisted Synthesis of Metal Nanoparticle /Reduced Graphene Oxide Nanocomposite

Carbon nanomaterial-ionic liquid hybrids represent a very interesting class of materials because of their unique properties that arising from the synergistic combination of both component. Owing to specific interaction between ionic liquids (ILs) and carbon nanomaterial, the surface properties can be modified leading to their improved dispersion in various media. Since the discovery of bucky gel, the role of ionic liquid on surface modification of carbon materials has been studied. In this article synthesis of graphene oxide and ionic liquid hybrid is investigated. Also their interaction analysis and role of ionic liquid in exfoliation of its sheets and dispersion have been studied. A simple and environmentally friendly approach for the preparation of graphene oxide sheets decorated with nickel nanoparticles has been developed by using ionic liquid. Besides, the ionic liquid also benefits the dispersion and size distribution of nanoparticles. In this work, ionic liquid–graphene nanosheets decorated nanoparticles (IL–RGO/nanoparticles) were synthesized. IL–GNs were characterized Fourier transform Infrared (FT-IR) spectroscopy which confirmed that IL was successfully covered on the surface of GNs.
