Abstract Postcombustion CO 2 capture has become a key component of greenhouse‐gas reduction as anthropogenic emissions continue to impact the environment. We report one‐step synthesis porous carbon materials using series task‐specific ionic liquids for adsorption . By varying structure liquid precursor, we were able control pore architecture and surface functional groups in this process leading adsorbents with high sorption capacities (up 4.067 mmol g −1 ) at 0 °C 1 bar. Added nitrogen led /N adsorption‐selectivity values ranging from 20 37 whereas simultaneously interaction energy was enhanced relative no added nitrogen.
