英文摘要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 are [DMAPAH][Formate] (2.5:1) + H2O (20 wt %) (4.61 mol/kg, 298 K, 0.1 MPa), [P-4444][Pro] + PEG400 (70 wt %) (1.61 mol/kg, 333.15 K, 1.68 MPa), [DMAPAH][Formate] (2.0:1) + MEA (30 wt %) (6.24 mol/kg, 298 K, 0.1 MPa), [TEMA][Cl]-GLY-H2O 1:2:0.11 (0.66 mol/kg, 298 K, 1.74 MPa), and [Ch][Cl]-MEA 1:2 + DBN 1:1 (5.11 mol/kg, 298 K, 0.1 MPa), respectively. All of these best candidates show higher CO2 solubility than their used pure ILs or DESs, evidencing that IL/DES-based hybrid solvents are remarkable for CO2 capture. For the summarized viscosity results, the presence of hybrid solvents in ILs and DESs can decrease their viscosities. The lowest viscosities acquired in this work for IL-H2O, IL-amine, DES-H2O, and DES-organic hybrid solvents are [DEA][Bu] + H2O (98.78 mol%) (0.59 mPa center dot s, 343.15 K), [BMIM][BF4] + DETA (94.9 mol%) (2.68 mPa center dot s, 333.15 K), [L-Arg]-GLY 1:6 + H2O (60 wt %) (2.7 mPa center dot s, 353.15 K), and [MTPP][Br]-LEV-Ac 1:3:0.03 (16.16 mPa center dot s, 333.15 K) at 0.1 MPa, respectively.
