説明:

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).
