Ionic Liquid-Functionalization Metal-Organic Framework for Efficient C2h2/Co2 Separation

Published: Jan. 1, 2025

Efficiently sieving C2H2 from CO2 remains a daunting challenge due to their similar molecular sizes and physical properties. To address this issue, we have developed novel strategy by functionalizing metal-organic frameworks with ionic liquid, making them effective adsorbents for CO2. The constructed model material of MIL-101-Cr-EMC (EMC = 1-ethyl-3-methylimidazolium chloride), exhibits both high capacity (94.2 cm3/g at 298 K 1.0 bar) outstanding selectivity over (8.5). Notably, 50 kPa, shows C2H2/CO2 5.4, which is 105 times higher than that the control group (MIL-101-Cr, 0.000054) under same conditions. This highlights critical role liquid functionalization in enhancing separation performance frameworks. work not only positions as promising candidate efficient separation, but also introduces developing advanced incorporation liquids into porous materials.
