In this study, N-doping noporous carbons (NNCs) were prepared from polypyrrole (PPY) by the ZnCl2 activation. The activation process was carried out under set conditions. The prepared NNCs was analyzed by X-ray photoelectron spectroscopy (XPS), N2/77 K full isotherms, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The CO2 adsorption capacity of the N-doped activated carbon was measured at 298 K and 1 bar. By dissolving the activation agents, the N-doped activated carbon exhibited high specific surface areas and high pore volumes. In addition, the N-doped activated carbons contained a high N content. The results showed that the N-doped activated carbons showed a very high CO2 adsorption capacity at 298 K and 1bar. |
