摘要：

The conversion of biomass into activated carbon nanofibers (ACNFs) has been extensively explored in recent years. In this work, ACNFs were fabricated from Napier grass fibers (NGFs) by chemical activation via KOH at various concentrations at high temperatures, followed by CO2 activation. SEM images revealed that the NGFsbased carbon nanofibers consisted of fibers with diameters ranging from 42 to 87 nm for NGFs-0.1 and 29-95 nm for NGFs-0.5. Additionally, N2 physisorption analysis demonstrated that NGFs-based activated carbon nanofibers (NGFs-0.3) had a high SBET of 756 m2 g- 1. At 1 A g- 1, NGFs-0.5 exhibited remarkable electrochemical behavior characterized by a specific capacitance of 325 F g- 1 with a specific energy of 45.1 Wh kg- 1 at a specific power of 145.23 W kg- 1. This work presents and provides new and innovative ideas for the future development of supercapacitor electrodes by utilizing affordable and sustainable materials.
