Breaking boundaries in CO2 capture: Ionic liquid-based membrane separation for post-combustion applications

An Ongoing Futuristic Career of Metal–Organic Frameworks and Ionic Liquids, A Magical Gateway to Capture CO2; A Critical Review

“…ILs are magical solvents with the unique features of nonvolatility, recyclability, and excellent thermal stability along with a wide range of tunability in the selection of various cations and anions . ILs are composed of the bulky organic cation having low molecular symmetry and the small organic/inorganic anion moieties that are in the molten form in their pure state. , The nature of high absorption capacity, biodegradability, and lower corrosivity associated with ILs makes them enables to be applied as a replacement solvent in place of existing volatile, corrosive, and degradation-originated amine-based solvents. , The unique chemical and physical characteristics of ILs provided them more opportunities to be utilized in numerous applications like catalysis, energy storage, electrochemistry, separation, and other applications. Moreover, the nature of high inflammability and high affinity toward CO 2 makes them enables to be utilized for gas separation applications for carbon capture …”

“…CO 2 is absorbed by the ILs under the influence of physical interactions between the anions and cations of the ILs with CO 2 molecules. Therefore, it can be said that the degree of CO 2 solubility in ILs is determined by the types of anions and cations present . In contrast to the cations present in ILs, anions are considered to have a greater impact on the absorption of CO 2 …”

Preparation of [BMIM]HSO4@SiO2 Ionic Liquid Microcapsules and Application to CO2 Adsorption

“…In this study, microcapsules were synthesized using the in-situ polymerization method, which can obtain microcapsules with a regular shape and good specific surface area and have an excellent ability to capture CO2. [BMIM]HSO4 IL was chosen as the core material, due to that compared to other References [10][11][12][13][14][15], this kind of ionic liquid has not been extensively studied and applied to CO2 absorption. Silicon oxide nanoparticles were chosen as the outer layer because of their good strength and permeability.…”
