Porous Liquids, a recent invention by James <i>et al.</i>, are a class of materials which may overcome some technological limitations of solid sorbents. Three generic types were first hypothesized (see figure 1) where Type 1 consists of a neat Porous Liquid, Type 2 being a porous molecular host dissolved in a hindered solvent and finally Type 3, a porous solid suspended in a hindered liquid. Until recently, Porous Liquids have been a challenge to synthesize, however, Type 3 Porous Liquids which incorporate the use of Metal Organic Frameworks and size excluded liquids can be synthesized and characterized with relative ease. The solubilities of gases in each of these Porous Liquids can be theoretically calculated and the experimental gas uptake measurements suggest that the adsorption behavior of these Type 3 Porous Liquids can be determined. Some Porous Liquids show as much as an eight-fold increase in adsorption (see figure 2). These liquids may ultimately provide an alternative to existing carbon capture technology based on amine solutions and may provide application in other areas of gas capture.
