- Coconut residue (CR) is used as a sustainable precursor for nanoporous carbon (NPC) production.
- NPC is synthesized via hydrothermal carbonization (HTC) followed by KOH activation at varying temperatures (700, 800, and 900 °C).
- Activation temperature affects the structure and electrochemical performance, with the highest surface area (1969 m² g⁻¹) at 900 °C.
- The NPC activated at 900 °C with a CR:KOH ratio of 1:2.5 achieved the highest specific capacitance (52 F g⁻¹ at 1 A g⁻¹).
- The study highlights CR as a low-cost, sustainable material for supercapacitor electrodes.
