Ecofriendly fabrication and theoretical insights of ascorbic acid assisted rGO electrodes for high performance solid state supercapacitors.

ABSTRACT: Graphene oxide (GO) and reduced graphene oxide (rGO) are promising materials for sustainable energy storage due to their excellent conductivity, large surface area, and chemical stability. However, conventional methods of reducing GO often involve toxic chemicals, raising environmental concerns. This study introduces a green solvothermal method to synthesize rGO using L-ascorbic acid and ammonia solution as reducing agents, producing a material referred to as G-rGO for supercapacitor applications. Theoretical calculations suggest that the reduction process significantly enhances the electronic properties and structural integrity of the material. X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and energy-dispersive X-ray (EDX) analysis confirmed the reductio
