Abstract

Abstract: We comprehensively report here a green route for synthesizing graphene oxide (GO) from waste Zn-C dry cell batteries. Here LiCl was used as electrolyte for the electrochemical synthesis of GO from graphite rods extracted from waste batteries. The satisfactory yield of 0.0305 g/h, formulated wholly through basic medium (at p H 9.36), was validated through confirmatory characterizations such as X-ray diffraction (XRD) analysis, Fourier-transform infrared spectroscopy (FTIR), UV-Vis and Raman spectroscopy, etc. A prominent diffraction peak around 26.70° in the XRD spectra and two prominent excitonic peaks around and in the Raman spectra were observed for the obtained samples. The overall scheme turned out to be engaging less reactants as well as facile; thus, converting a waste material to a useful product.
