Introduction
Strategies to mitigate greenhouse effects caused by the increasing levels of carbon dioxide in the atmosphere have seen much development in the past decade, specifically in research areas concerning carbon capture and storage (CCS) or utilization (CCU). The utilization of CO2 is often seen as more attractive over storage, especially if the products of the bulk conversion are of economic importance. However, CO2 is thermodynamically stable due to its highly oxidized nature, rendering it inactive for a number of transformations. In this entry, we will summarize recent developments of ionic liquid (IL)-promoted or IL-mediated transformations of CO2.
ILs are generally defined as salts that have a melting point of below 100 °C, consisting of discrete cations and anions. ILs based on ammonium, pyridinium, and phosphonium salts have been reported, but imidazolium salt ILs have emerged to be a prominent class of ILs on its own. This is due to its ease of synthesis, allowing for...
