Abstract

carbon structure and preserved porosity. Electrochemical impedance spectroscopy confirmed low charge transfer resistance and favorable capacitive behavior for rGO@48, while rGO@72 showed the poorest performance due to restacking and limited ion diffusion. These findings indicate that a 48 h hydrothermal carbonisation followed by controlled reduction yields promising electrochemical properties for supercapacitor electrode application.
