A hierarchically porous carbon monolith (97% porosity) was generated through the carbonization of an emulsion-templated monolith formed from a chain extended, urea-based, deep-eutectic polymer. The highly interconnected micrometer-scale porous structure had a high specific surface area (812 m2 g−1, largely microporous) and exhibited promising results for aqueous solution sorption applications.

The aim of this research is to find out the potential usage of water miscible ammonium based ionic liquids (ILs) towards CO2capture. To measure the solubility of CO2in 55 wt. % aqueous solution of Tetra butyl ammonium hydroxide (TBAOH), the experiments were carried out using high pressure solubility cell. Solubilities were determined in the temperature range of (303.15 to 333.15) K by varying the pressure from (2 to 10) bar and are reported as loading capacity (mol CO2/mol TBAOH). The solubility of CO2in this aqueous IL decreased with increasing temperature and increased with increasing pressure.
