Although the use of ‘task-specific’ amine-functionalized imidazolium-based ionic liquids (ILs) such as [NH2emim][BF4] and conventional imidazolium-based ILs [bmim][BF4]), as absorbents for CO2 capture, possesses some unique advantages, they have a number of disadvantages when independently used for CO2 capture. This study examined a series of binary liquid mixtures of [NH2emim][BF4] and [bmim][BF4] for CO2 capture, exploiting the advantages and reducing the disadvantages of each of the components. The CO2 absorption performances of the mixtur...
