Cover Picture: Theoretical Screening of Ionic Liquid Solvents for Carbon Capture (ChemSusChem 7/2009)



original image

The cover picture shows the molecular modeling of CO2 capture by an ionic liquid membrane. A typical fossil-fuel plant (top left) produces significant CO2 emissions and emissions of other greenhouse gases. A membrane based on ionic liquids may absorb such emissions. The chemical structure of the constituting cation–anion pair is also shown. In a Communication on p. 628, A. Maiti describes how a quantum-chemistry-based solvation model is used to design and screen candidates for high-efficiency capture.
