Abstract Physisorption presents a promising alternative to cryogenic distillation for capturing the most potent greenhouse gas, SF6, but existing adsorbents face challenges in meeting diverse chemical and engineering concerns. Herein, with insights into in-pore chemistry industrial process design, we report systematic investigation that constructed two novel low-cost composites pellets (Al(fum)@2%HPC Al(fum)@5%Kaolin) coupled an innovative two-stage Vacuum Temperature Swing Adsorption (VTSA) ultra-efficient recovery of low-concentration SF6 from N2. Record-high selectivities (> 2×104) dynamic capacities (~2.7 mmol/g) were achieved, while exceptional productivities (~58.7 L/kg), yields (~96.8%), recyclability (~1000 cycles) demonstrated fixed-bed adsorption-desorption experiments under mild regeneration conditions. 2D solid-state NMR/in-situ FTIR, DFT-D binding/diffusion simulation analyses revealed multi-site binding mode ultra-fast diffusion within channels. The proposed VTSA processes successfully met dual stringent requirements both environmental protection electricity equipment operation: 99.91% accompanied purity/working capacity 99.91%/2.1 mmol/g, which significantly outperformed employed adsorbent zeolite 13X showed only 19% energy consumption distillation.

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.
