The Reinforced Separation of Intractable Gas Mixtures by Using Porous Adsorbents

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(41)

Published: Aug. 19, 2024

Abstract This review focuses on the mechanism and driving force in intractable gas separation using porous adsorbents. A variety of mixtures have been discussed, including air separation, carbon capture, hydrocarbon purification. Moreover, systems are categorized according to distinctly biased modes depending minor differences kinetic diameter, dipole/quadruple moment, polarizability adsorbates, or sorted by varied occasions (e.g., CO 2 capture from flue air) forces (thermodynamic molecular sieving). Each section highlights functionalization strategies for materials, like synthesis condition optimization organic group modifications cation exchange heteroatom doping zeolites, metal node‐organic ligand adjustments MOFs. These subsequently associated with enhanced adsorption performances (capacity, selectivity, structural/thermal stability, moisture resistance, etc.) toward analog mixtures. Finally, this also discusses future challenges prospects materials separation. Therein, combination theoretical calculation parameters adsorbents may great potential, given its fast targeting candidate deeper insights into confined pores cages.

Journal of the American Chemical Society, Journal Year: 2024, Volume and Issue: 146(14), P. 9939 - 9946

Published: March 28, 2024

Selective recognition of 1,3-butadiene from complex olefin isomers is vital for purification, but the lack porous materials with suitable pore structures results in poor selectivity and low capacity C4 separation. Herein, two sulfonate-functionalized organic frameworks, ZU-601 ZU-602, are designed show impressive separation performance toward olefins. Benefiting aperture size caused by flexibility coordinated ligand, ZU-601, ZU-602 that pillared different sulfonate anions could discriminate high uptake ratio: 1,3-butadiene/1-butene (207), 1,3-butadiene/trans-2-butene (10.1). Meanwhile, their layer-stacked structure enables utilization both intra- interlayer space, enhancing accommodation guest molecules. exhibits record adsorption 2.90 mmol g–1 (0.5 bar, 298 K) among reported flexible selectivity. The breakthrough experiments confirm superior ability even all five isomers, molecular-level structural change well elucidated via powder, crystal analysis, simulation studies. work provides ideas advanced design simultaneous challenging separations.
