Abstract Fluorinated gases (F-gases) play a vital role in the chemical industry and fields of air conditioning, refrigeration, health care, organic synthesis. However, direct emission waste containing F-gases into atmosphere contributes to greenhouse effects generates toxic substances. Developing porous materials for energy-efficient capture, separation, recovery is highly desired. Recently, as designable adsorbents, metal–organic frameworks (MOFs) exhibit excellent selective sorption performance toward F-gases, especially recognition separation different with similar properties, showing their great potential control recovery. In this review, we discuss capture azeotropic, near-azeotropic, isomeric mixtures various application scenarios by MOFs, specifically classify analyze molecular interaction between interpret mechanisms underlying high regarding both adsorption capacity selectivity, providing repertoire future design. Challenges faced transformation research roadmap MOFs adsorbent technologies are also discussed, areas endeavors highlighted.

Abstract Separating n‐butane/iso‐butane is a challenging and energy‐intensive task in the petrochemical industry. There have been only several adsorbents reported for C4 paraffins separation while they are confronted real‐world applications with either poor selectivity or low n‐butane uptake capacity. In this study, fluorinated zinc‐based metal‐organic framework (MOF), Znpyc‐CF 3 , derived from Znpyc‐CH developed, which has fluorine‐containing functional groups on pore surface that can enhance interaction linear n‐butane. Remarkably, porous material demonstrates both high (55.5 cm g⁻¹) excellent (IAST = 187) at ambient temperature. Multicycle breakthrough experiments confirmed its practical performance real gas mixtures. exhibits outstanding stability, maintaining structural integrity after repeated sorption cycles dynamic tests under dry highly humid conditions. The preferential adsorption mechanism of further elucidated through Grand Canonical Monte Carlo (GCMC) simulations Density Functional Theory (DFT) calculations. Overall, research presents an efficient stable adsorbent butane isomers.

The development of nanoporous metal–organic frameworks (MOFs) capable effectively separating and purifying CH4 is significant importance. High surface polarity suitable pore diameter are two key factors that can synergistically enhance separation performance. Herein, we report hydroxyl-functionalized Al-MOFs (CAU-1-OH CAU-1-(OH)2) for the purification natural gas. They both possess different types nanocages as well a densely surface. Significantly, CAU-1-(OH)2 demonstrated exceptional selectivity in C3H8/CH4 (50:50, v/v) C2H6/CH4 v/v), with values 990 36, respectively, surpassing those most reported porous materials. dynamic breakthrough experiment ternary mixture generate pure exceeding 3.46 mmol g–1, which adequately demonstrates actual performance CAU-1-(OH)2. Finally, molecular simulations situ infrared experiments verified high affinity toward C3H8 C2H6, giving rise to loading capacity C2H6. These results support potential double hydroxyl-modified nanomaterial methane from
