Abstract
Carbon dioxide capture and storage technology has received a worldwide attention in the last years due to the environmental impact and pronounced ecosystem change produced by CO2. Ionic liquids (ILs), also called green solvents, show a great potential as adsorbents for CO2. For a more efficient use of ILs, the concept of ILs supported onto porous materials has been developed. Due to their high specific surface porosity and affinity for CO2 adsorption, metal-organic frameworks (MOF) represent a very interesting candidate for supporting ILs. Tunable physicochemical properties of both MOFs and ILs and their unlimited number of possible combinations offer opportunities to tailor the structures for the best CO2/gas adsorption performance. In this review, we have discussed studies carried out to date on the ILs supported on MOFs and their possible applications in CO2/gas adsorption.
