## Description

- description: We present the energy performance of ultrahigh surface area nanoporous
    carbon materials having abundant hierarchical micro/mesopores obtained by in situ
    potassium carbonate (K2CO3) activation of polyacrylamide (PAM) hydrogel. The resulting
    nanoporous carbon materials obtained by the carbonization of the hydrogel in the
    temperature range 600 to 900 °C possess high BET surface areas up to ca. 3038
    m2 g-1 for the material prepared at 800 °C. Electron microscopy analyses revealed
    the formation of micro/mesoporous amorphous carbon structures. Surface composition
    and nitrogen and oxygen doping of the carbon matrix were verified by X-ray photoelectron
    spectroscopy (XPS).
