The hybrid composites consist of aluminum terephthalate metal-organic framework (AlTp) impregnated of 1-butyl-4-methyl pyridinium and 1-butyl-3-methylimidazolium-based ionic liquids (ILs) with different anions, viz. tetrafluoroborate ([BF₄]^-), thiocyanate ([SCN]^-), chloride ([Cl]^-), and bromide ([Br]^-). ILs-impregnated AlTp synthesized was characterized using scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), the thermogravimetry analysis (TGA) and Fourier transform infrared (FTIR) sScientific reports3227https://www.ebi.ac.uk/biostudies/studies/S-EPMC9958030biostudies-literatureImproving performance of mesoporous MOF AlTp impregnated with ionic liquids for CO₂ adsorption.PMC9958030Noorani NMehrdad AfalseImproving performance of mesoporous MOF AlTp impregnated with ionic liquids for CO₂ adsorption.In this work, the CO₂ adsorption performance of metal-organic frameworks (MOFs) impregnated with ionic liquids (ILs) was studied using quartz crystal microbalance (QCM) at the temperature of 298.15 K and pressures up to 5 bar.
