## Description

- description: 'This research reports the synthesis of activated nanoporous carbon
    material from Phyl-lanthus emblica (Amala)- a Biomass material which is eco-friendly,
    economical, and sus-tainable precursor to prepare activated carbon, by zinc chloride
    (ZnCl2) activation at vari-ous temperatures (500-700 °C) under the nitrogen gas
    atmosphere. The sample carbonized at 700 °C (AmC_Z700) attained a high specific
    surface area 1436 m2 g-1 and a total pore volume of 0.962 cm3 g-1 and the electrode
    showed excellent supercapacitance performance, attaining a high specific capacitance
    of 263 F g-1 at a current density of 1 A g-1 followed by 55% capacitance retention
    at 50 A g-1. '
