Abstract: The CO2 solubilities (including CO2 Henry’s constants) and viscosities in ionic liquids (ILs)/deep eutectic solvents (DESs)-based hybrid solvents were comprehensively collected and summarized. The literature survey results of CO2 solubility illustrated that the addition of hybrid solvents to ILs/DESs can significantly enhance the CO2 solubility, and some of the ILs-based hybrid solvents are super to DESs-based hybrid solvents. The best hybrid solvents of IL–H2O, IL–organic, IL–amine, DES–H2O, and DES–organic a… Show more

“…Jiang et al 57 considered DBN:2imidazolidone, or DBN:1,3-dimethylurea or DBN:dimethylurea DESs, also reporting an improvement of capturing ability, especially for 2-imidazolidone. Additional relevant studies considering superbases were reported by Zhang et al 58 (considering DBN) and Yan et al 59 (considering DBU in superbase ILs mixed with ethylene glycol for DES development) showing in all the cases reversible and efficient CO 2 adsorption, as confirmed by the analysis reported by Liu et al 60 Nevertheless, these superbase-based DESs systems may present problems related to the increase of viscosity upon CO 2 capture, the poor performance of desorption cycles, with only 23% release of captured CO 2 upon heating to 60 °C. 56 Similarly, that of superbase−DESs has been questioned in the literature, 61 considering the poor thermals stability of superbases in certain solvents, as well as the extreme sensitivity of superbases toward water, 62 which would require special conditions from their preparation and handling hindering scaling up.…”

“…In this project, MEA and tetrabutylphosphonium methanesulfonate ([TBP][MeSO 3 ]) were selected to be mixed, producing aqueous hybrid solvent for CO 2 removal. The MEA concentration was kept constant at 30 wt% as per typical amine concentrations used in commercialized CO 2 absorption technology [13,14]. The selection of [TBP][MeSO 3 ] was based on the results of a screening study using the Conductor-like Screening Model for Real Solvents (COSMO-RS) by Azman [15].…”

“…During the preparation and storage of DESs, purity and water content are key factors. Due to the hygroscopic nature of some components of DESs, such as choline-based DESs, the physical and chemical properties of DESs can change with the addition of excess water, affecting their subsequent application . Therefore, sealing is required during preparation and storage.…”
