Enhancement of CO2 adsorption and separation in basic ionic liquid/ZIF-8 with core-shell structure
CHEMICAL COMMUNICATIONS(2024)
Abstract
A novel strategy was proposed to improve the performance of gas separation in nano-materials, by fabricating a core-shell structure out of the basic ionic liquid ([Emim]2 [IDA]) and zeolitic imidazolate framework (ZIF-8). The [Emim]2 [IDA]/ZIF-8 exhibits a remarkable CO2 adsorption capacity of 14 cm3 g-1 at 298 K and 20 kPa, the ideal selectivity of CO2 /N2 is as high as 104 and CO2 /CH4 is 348 at 298 K and 100 kPa, which are much higher than the CO2 adsorption capacity (4.3 cm3 g-1) and the selectivity (SCO2 /N2 = 7.4, SCO2 /CH4 = 2.7) of ZIF-8. This work could pave the way for designing advanced nanostructures tailored for gas separation.
