## Description

- description: 'Here, we report on the fabrication of nanoporous activated carbon
    materials from a novel biomass precursor Achyranthus bidentata (Datiwan), using
    a low-energy method (carbonized at 500 °C). The effects of chemical activators
    (phosphoric acid (H3PO4), potassium hydroxide (KOH), and zinc chloride (ZnCl2)
    on surface textural properties and energy storage capacity were systematically
    studied. The H3PO4 and ZnCl2 activated samples (DAC-H500, DAC-Z500) exhibited
    the specific surface area of 724 and 758 m2 g-1, respectively, and retained abundant
    surface oxygen functionalities, thereby leveraging decent specific capacitance
    of 201 F g-1 and 140 F g-1 at 1 A g-1 with 51% and 61.3% retention of their initial
    capacitance values at 10 A g-1. '
