Abstract

Metal free N-containing compounds grafted graphene oxide (GO) composites have played crucial role in energy storage applications. In this work, covalent functionalization of graphene oxide (GO) with diethylenetriamine (DETA) was achieved by a simple addition reaction. Various spectroscopic and microscopic techniques such as X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), Raman and thermogravimetric analysis (TGA) were performed to confirm the structure of the resultant GO/DETA. Results confirmed that the GO/DETA have N-rich group on the surface of GO. Cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy were carried out for GO and GO/DETA. The functionalized GO material, GO/DETA, showed superior capacitive behaviour of 255 F/g in 6 M KOH at 10 mV s-1 when compared to fresh GO (136 F/g). The specific capacitance retention value of GO/DETA was found to be 92%, revealed high stability of GO/DETA.
