Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Postcombustion CO₂ capture has become a key component of greenhouse‐gas reduction as anthropogenic emissions continue to impact the environment. We report a one‐step synthesis of porous carbon materials using a series of task‐specific ionic liquids for the adsorption of CO₂. By varying the structure of the ionic liquid precursor, we were able to control pore architecture and surface functional groups of the carbon materials in this one‐step synthesis process leading to adsorbents with high CO₂ sorption capacities (up to 4.067 mmol g⁻¹) at 0 °C and 1 bar. Added nitrogen functional groups led to high CO₂/N₂ adsorption‐selectivity values ranging from 20 to 37 whereas simultaneously the interaction energy was enhanced relative to carbon materials with no added nitrogen.</p> </abstract>
