Supercapacitors are energy storage devices known for their rapid charging time, long cycle life, and high electrochemical stability. One of the key components in a supercapacitor is the carbon electrode. This study aims to synthesize carbon electrodes derived from green grass jelly leaf biomass (Premna oblongifolia Merr) by incorporating nitrogen doping using thiourea. The synthesis process began with pre-carbonization at 200 °C for 2 hours and 30 minutes, followed by chemical activation using 0.3 M KOH, carbonization at 600 °C, and physical activation at 800 °C. Thiourea was used in different masses: 0 g (ADC-00), 0.1 g (ADC-01), and 0.3 g (ADC-03). Physical characterizations were performed using XRD, SEM, EDX, and BET. XRD results indicated the presence of two Landau peaks at 2θ angles around 23° (002 plane) and 44° (100 plane), confirming the microcrystalline structure. SEM images revealed that nitrogen doping improved pore uniformity and surface morphology. EDX analysis showed that ADC-03 had the highest nitrogen content of 6.3 %. The highest specific surface area of 487,210 m²/g was obtained from BET analysis. Electrochemical testing in 1 M H₂SO₄ electrolyte revealed that ADC-03 achieved the highest specific capacitance of 431 F/g (CV) and 329 F/g (GCD). These results confirm that the addition of 0.3 g thiourea effectively enhances the physical and electrochemical performance of carbon electrodes derived from green grass jelly leaf biomass, demonstrating their potential for supercapacitor applications.
Keywords: green grass jelly leaf, carbon electrode, thiourea, nitrogen doping, supercapacitor.
