Summary: This computational study investigates the reactions between CO2 and various substrates using a Bronsted acidic ionic liquid as a catalyst. The results show that ethylenediamine (EDA) is the most effective substrate for fixing CO2, and nonpolar solvents enhance the reaction. Modifying the ionic liquid with selenium can also be a viable option. Molecular dynamics simulations reveal that the ionic liquid ion pairs can facilitate the nucleophilic attack on CO2 through noncovalent interactions.
