Resumen

Modern society's biggest challenges are affordable, clean energy production and storage. Thus, recent research aims at the discovery of novel electrode materials for enhanced energy production and storage. Herein, nitrogen-implanted carbon particles were synthesized for the first time from the Acorus Calamus for the symmetric supercapacitor application. The KOH-activated carbon particles at 750 °C (C-750) under a nitrogen atmosphere revealed the better structural, textural, morphological, and electrochemical performance. The BET analysis confirmed that the C-750 carbon nanoparticles tremendously enhanced the surface area of about 3551.07 m2/g. Further, the pore size and pore volume were obtained from BJH analysis that showed 3.70 nm and 0.51 cc/g, respectively. The high surface area along with the mesoporous nature of the C-750 sample effectively enhanced the specific capacitance to 354.44 Fg−1 at 1 Ag−1 using a 6 M KOH electrolytic solution. Further, the enhancement of energy and power density of the C-750 was observed at about 47.2 Whkg−1 and 16,000 Wkg−1, respectively.
