Synthesis and characterization of reduced graphene oxide/Ag<inf>2</inf>S nanocomposites by co-precipitation method using thiourea as sulfur source and reducing agent

Graphene based nanocomposites are emerging as a new class of materials for many applications. Reduced graphene oxide/Ag2S composites were synthesized through a simple coprecipitation method. The composite materials were characterized by X- ray diffractometer (XRD), Fourier transform infrared (FTIR), Ultraviolet – Visible (UV-Vis) and Raman spectroscopy measurements. The chemical state and its Binding Energy investigations of the rGO/Ag2S were carried out by X-ray photoelectron spectroscopy (XPS). The surface morphology of the composite material was studied by Field emission- Scanning electron Microscope (FE-SEM) and Transmission electron Microscope (TEM) shows that the Ag2S nanoparticles are heavily deposited on the surface of the reduced graphene Oxide layers.
