The utilization of pure ionic liquids (ILs), as environmentally green and soft chemical solvents, is restricted in the CO2 capture industry due to their high viscosity and fair conductivity. In this paper, the novel comprehensive models were developed for accurate estimation of density, dynamic viscosity, surface tension, and electrical conductivity of a novel protic amino acid‐functionalized IL, namely monoethanolamine glycinate, [MEA][GLY], in the temperature range of 303.15–323.15 K at two different intervals of water content (5–20 wt%, and 25–100 wt%). The results of the suggested models revealed that the density, viscosity, and surface tension of [MEA][GLY] decline substantially with rising temperature, while the electrical conductivity presents an adverse trend. Additionally, the impact of varying the concentration on the density and viscosity of the IL solution is more significant than the solution temperature, particularly at high concentrations of the IL. Moreover, a second‐order polynomial equation was suggested to depict the equilibrium pressure dependence of CO2 loading capacity of aqueous [MEA][GLY] in IL, at various equilibrium pressures of 1–7 bar.

Capture and utilization or storage of CO2 have been considered as the primary options to reduce the impact on the climate caused by CO2 emissions. Several technological approaches have been proposed depending on the point of actuation (precombustion, postcombustion, or oxyfuel combustion), but absorption processes are still the most extended solution implemented in the industry. Alkanolamines are typical solvents used for CO2 capture, even though they have a noticeable negative impact on the environment. Amino acids and their salts have been appointed as alternative solvents since their functional group is similar to that of alkanolamines but presenting better properties. In addition, they show very good performance in CO2 capture. This manuscript reviews the state of the art of the use of amino acids in CO2 capture and the main technologies involving the application of these solvents.

“…Among all of the CO 2 -capturing materials, ionic liquids distinguish themselves from others due to their designability, negligible vapor pressure, good thermal stability, etc. − Based on these properties, many scientists have attempted to utilize ionic liquids for CO 2 capture. For ionic liquids such as azole-based ionic liquids, − amine-functionalized ionic liquids, − and amino acid ionic liquids, − equimolar or multimolar chemisorption process is often expected. For physisorbing ionic liquids, the adsorption process is quick and facile, while the molar adsorption fraction is often lower when compared to that of chemisorbents.…”

Amino-functionalized ionic liquids (IL) are often applied to fix CO2. However, as far as we know, none of them have ever been reported to exhibit considerable physical CO2 capture. Herein, we describe an amino-functionalized room-temperature ionic liquid, 1-butyl-3-methylimidazolium 3-amino-1H-1,2,4-triazolate ([Bmim][ATZ]), with an unusual ultrafast physical CO2 capture at room temperature and atmospheric pressure. Within the time needed for a chemisorbent to reach an equilibrium, 15 adsorption and desorption cycles are finished for [Bmim][ATZ], with an accumulative molar ratio of up to 2.04. The CO2/IL ratio for one adsorption process reaches 0.14, which is 4 times the highest recorded physical CO2 solubility by [thtdp][Cl] (trihexyltetradecylphosphonium chloride). The first theoretical study on anion–anion interactions of ionic liquids is reported, which rationalizes the inhibition of chemical adsorption. These results provide a new perspective on the aspect of CO2 capture, as well as designing of ionic liquids.
