Abstract Ionic liquids and ionic liquid‐based materials were emerging as sorbents for carbon dioxide capture. Amino‐imidazolium materials, a kind of sorbents, were synthesized and characterized for the sorption of carbon dioxide. The ionic liquid‐modified materials have higher sorption capacity of carbon dioxide than the unmodified sorbents. The effects of pressure and temperature were investigated. The adsorbed amount of carbon dioxide increased with the increasing pressure and the ionic liquid‐based polymer show higher sorption efficiency than that of ionic liquid‐based silica.
