Optical Characterization and Electrochemical Properties of Cd(1-x)Cu(x)S/rGO Composites Synthesized Through Reflux Method

摘要

Cd(1-x)Cu(x)S/rGO composites were synthesized through reflux method. The composites were characterized by using X-ray diffractometer (XRD), Fourier transform infrared (FTIR), Raman spectroscopy, Thermogravimetric Analysis (TGA). The presence of elements was confirmed by Xray photoelectron spectroscopy. The morphological studies FE-SEM and TEM shows that the Cd(1-x)Cu(x)S nanoparticles were deposited on the surface of reduced graphene oxide sheets. The electrochemical property was studied by CV analysis, which indicates the introduction of Cu ions into CdS nanoparticles on to the rGO sheets results the increase in the integral area and current, compared with that of pure CdS nanoparticles and CdS/rGO composites. This work provides the convenient chemical route to prepare reduced graphene oxide sheets and its composite materials. This new composite material could be useful for energy storage devices, photocatalysis and in other fields.
