Effect of the Graphene Sheets on the Physical Properties of Copper Sulfide Nanoparticles

Abstract

This paper shows the synthesis of copper sulfide (CuS) nanoparticle by co-perception method at low temperature and the synthesis of copper sulfide/graphene sheets (CuS/Gs) nanocomposite by hydrothermal method at 120 °C. The structure, surface morphology and size of nanoparticles (NPs) are discussed and analyzed by X-ray diffraction analysis (XRD), energy dispersive X-ray analysis (EDX) and transmission electron microscopy (TEM). The obtained nanoparticles have sizes between (4-10 nm). We are studied the effect of graphene-based nanoparticles nanocomposite on the thermal properties by thermogravimetric analysis (TGA). The photocatalysis properties are investigated at different conditions. The result shows that the graphene sheet (Gs) nanocomposite effect the composition and the thermal properties of nanoparticles.
