A rapid, efficient, green and eco-friendly approach for the preparation of reduced graphene oxide (rGO) using
Plectranthus amboinicus (Indian borage) leaves extract (PAE) is explored in this study. The improvement in the reduction process was studied by varying the concentration of graphene oxide (GO), temperature and time duration. The physical and chemical properties of rGO are studied using Raman spectroscopy, Fourier transform infrared spectroscopy, X-raydiffraction (XRD) and field emission scanning electron microscope. The result obtained from XRD analysis confirms the removal of an oxygen-containing functional group of GO significantly by PAE. Raman analysis showed a higherID/IG ratio for rGO (1.297) than GO (1.07), which indicates a higher level of disorder in the rGO with a decrease in the average size of the sp$^2$ domain. From the electrochemical studies, a significant specific capacitance of 92.05 F g$^{–1}$ (5 mV s$^{–1}$) is obtained from the cyclic voltammetry (CV) curves and 73.20 F g$^{–1}$ (0.1 A g$^{–1}$) from the galvanostatic charge–discharge (GCD) curve.
