摘要: Gas separation performance of the zeolitic imidazolate framework (ZIF-8) was improved by incorporating an ionic liquid (IL), 1-n-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]). Detailed characterization based on X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed that morphology ZIF-8 remains intact upon IL incorporation up to 28 wt %. Thermogravimetric analysis indicated presence direct interactions between metal organic (MOF). FTIR spectroscopy illustrated anion shared [BMIM]+ cation. Adsorption isotherms CO2, CH4, N2 measured for pristine IL-loaded samples, complemented grand canonical Monte Carlo (GCMC) simulations, showed these influence gas uptake ZIF-8. CH4 uptakes decreased in whole pressure range, while CO2 first increased approximately 9% at 0.1 bar 20 % sample then d...
