Abstract :A flexible, free-standing and durable CuS/reduced graphene oxide insert ignore into journalissuearticles values(rGO); composite paper electrode was prepared with a simple electrochemical deposition of CuS structures on the surface of the rGO paper electrode. CuS/rGO composite paper electrode was characterized by using scanning electron microscopy insert ignore into journalissuearticles values(SEM);, X-ray photoelectron spectroscopy insert ignore into journalissuearticles values(XPS);, X-ray diffraction insert ignore into journalissuearticles values(XRD);, and Raman spectroscopy. The morphological characterization displayed that the surface of the rGO paper electrode was covered with ball-like CuS structures. Microstructures of rGO and CuS/rGO papers and the intensity of surface defects were compared with Raman spectra. Electrochemical studies exhibited that as-prepared CuS/GO composite paper electrode has very high electrochemical activity.
