Highly porous N-doped activated carbon monoliths (ACMs) are fabricated by carbonization and physical activation of mesoporous polyacrylonitrile (PAN) monoliths in the presence of CO 2 . The monoliths exhibit exceptionally high CO 2 uptake; 5.14 mmol g −1 at ambient pressure and temperature and 11.51 mmol g −1 at ambient pressure and 273 K.
