    Carbon-based materials, due to their unique structural and physicochemical properties, are used in various environmental and energy applications. The present investigation reports a sustainable approach to valorise Gliricidia sepium (GS) into porous carbon with a large surface area. Carbon was synthesized through carbonization and KOH activation, with varying KOH-to-carbon ratios. The influence of the KOH activation ratio showed variation in structural and morphological character in activated carbon, which influenced the electrochemical and dye adsorption performance. Among the samples, GSC5K achieved a specific surface area of 2670 m2 g−1 with a pore volume of 1.33 cm3 g-1, enabling efficient ion transport and adsorption. Further electrochemical studies demonstrated a notable specific capacitance of 329 F g−1 at 5 mV s−1, positioning GSC5K as a strong candidate for supercapacitor application. Additionally, GSC5K demonstrated enhanced methylene blue adsorption (250 mg g−1) achieving complete removal within 120 s under refined kinetic monitoring, surpassing the adsorption capacity of commercial activated carbon. Thus, the work highlights an enhanced GS-derived carbon for sustainable energy storage and wastewater treatment.
