Abstract

Graphene is a material that has amazing electrical and optical properties. This research will discuss the effect of adding Cobalt Sulfide (CoS) on the reduction of graphene oxide (RGO) by using variations in the CoS ratio to improve the electrochemical properties of RGO. Graphene oxide (GO) is reduced by adding (Co(NO3)2.6H2O, thiourea (CH4NS) and added with ethylenediamine, then all materials reacted via solvothermal process. RGO that has been successfully synthesized will be characterized to determine the structural and chemical characteristics of the synthetic material by using X-Ray Diffraction (XRD), Fourier Transform Infra-Red Spectroscopy (FTIR), Scanning Electron Microscopyy (SEM), and Spectrophotometer UV-Vis. According to the results characterizations there are many differences on the optical characteristic and morphology on each phase of GO, RGO and RGO CoS.
