CO₂ Capture by Imidazolate-Based Ionic Liquids: Effect of Functionalized Cation and Dication

Given the fact that the basicity of imidazolate was higher than that of acetate, imidazolate-based ionic liquids (ILs) were developed to be studied. By combining six different cations, including traditional cation, functionalized cation, and dication, together with imidazolate, a series of ILs were prepared and found to be effective for CO2 capture. The mechanism of the studied ILs was proposed as the formation of the carboxylation reactions on...
