Enhanced selective adsorption of CO2 on nitrogen-doped porous carbon monoliths derived from IRMOF-3.

The N-doped porous carbon monoliths prepared by direct carbonization of IRMOF-3, through an in situ activation and self-templating process, were found to exhibit significantly enhanced performance for the selective adsorption of CO2 compared to pristine IRMOF-3. The transformation from the microporous structure to the meso-macroporous structure opens the pathway for CO2 to more easily access the nitrogen anchors.
