Why are Ionic Liquids Attractive for CO2 Absorption? An Overview
Abstract
As the climate debate is hotting up, so is the (re)search for finding powerful new materials for the efficient and cost-effective removal of CO2 from flue-gas streams from power plants and other emission sources. Ionic liquids (ILs), exhibiting higher CO2 solubility than conventional organic solvents, have received considerable interest as new CO2 absorbents. The present paper evaluates the advantages and disadvantages of ILs, and provides an overview of the recent developments of ILs for CO2 capture. In conventional ILs, CO2 is absorbed by occupying the free space between the ions through physical absorption mechanisms. As another promising strategy, task-specific ILs have been studied that, by attaching functional groups to the ions, allow the formation of chemical bonds to improve the overall absorption capacity during the CO2 capture process. Other strategies include using ILs as reaction media or as selective absorption materials.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
