Abstract

This work aims to explore the structural, morphological, and electrochemical features of graphene oxide. The study investigates graphene oxide's electrochemical behavior in supercapacitor applications. The graphene oxide was synthesized using the modified Hummer's method. XRD, Raman spectroscopy, and (HR-TEM) were used to investigate structural and morphological properties. The results confirmed the formation of the typical hexagonal structure of the graphene oxides. Raman spectrum showed two distinct G (primary mode of graphene) and D (defect or disorder mode) Raman modes at 1592 cm-1 and 1349 cm-1, respectively, in addition to D+D' and 2D modes. The electrochemical measurement revealed that the GO electrode has a specific capacitance of 38.33 F/g at a current density of 5 A/g in a 1 M KOH electrolyte with a very low charge transfer resistance of 0.97Ω. These findings suggested that this straightforward method can be used to create various graphene-derived electrodes for upgrading current supercapacitors.
