Abstract

The co - precipitation approach was used to construct reduced graphene oxide (RGO) – supported Cu nanoparticles. PXRD, EDX, and TEM examination validated the crystalline size and functional groups as well as morphological behaviour of these nanoparticles. The powder XRD findings of rGO and Cu-rGO nanocomposites are used to estimate grain size, dislocation density, and micro strain. Cu-rGO nanoparticles are opaque in the optical and near infrared domains, with a reduced cut-off wavelength of 233 nm, according to UV-Visible absorption spectra. The band gap strengths (Eg) of rGO and Cu-rGO nanocomposites were found to be 1.5 and 2.31 eV, correspondingly. Cu-rGO d-spacing values from XRD and Cu-rGO d-spacing values from the SEAD pattern were quite similar. In multi scan rate, the specific capacitance values of rGO and Cu-rGO estimated from CV increased, as did the specific capacitance value.
