The present study reveals that synthesized Graphene oxide (GO) by using a modified Hummer’s method and then by applying heat treatment yielded reduced Graphene oxide (rGO). The phase purity and crystal structure of the synthesized rGO was determined using X-ray diffraction (XRD). Which confirms the production of reduced graphene oxide. Also, Scherrer's equation was used for average crystallite size calculation. Fourier transform infrared spectroscopy (FTIR) was used to identify the molecular vibrations and functional groups which confirms the presence of C=C and C-O bonds in the sample. The surface morphology of the produced samples was investigated using a field emission scanning electron microscope (FESEM), which revealed that the surface of the rGO sheet is smooth. The optical characteristics are measured using a UV-Visible spectrometer. The band gap is calculated by the tauc plot analysis. the band gap of the sample is found to be 1.92 eV. In this study, efforts were attempted to manufacture reduced graphene oxide nanosheet by modified hummer’s method. |
