Graphene-Nickel Oxide (G-NiO) nanocomposites with different morphologies, such as nanowires (NWs), nanorods (NRs) and nanoparticles (NPs), are synthesized by a combination of liquid-phase exfoliation (LPE) and hydrothermal methods. The synthesis of Graphene, morphology of Nickel Oxide (NiO) thin films and concentration of elements are analyzed using Raman Spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) and Energy-dispersive X-ray spectroscopy (EDS), respectively. Furthermore, the capacitive behavior of nanocomposites is investigated using the Cyclic Voltammetry (CV). The optical properties of samples are extracted from measured absorbance spectra. Our results show that G-NiO NWs with the longest length have the largest specific capacitance (SC). In addition, optical data revealed that the adding Graphene to NiO thin films decreased the optical bandgap as well as the optical conductivity of nanocomposites increased with photon energy due to excitation electrons.
