Abstract One‐step purification of ethylene (C 2 H 4 ) from complex crude C products containing acetylene ), ethane 6 and carbon dioxide (CO impurities is highly critical desirable. Herein, we customize the pore environments with versatile dense adsorption sites in a novel interpenetrated adsorbent, Zn‐mtz‐ina, to simultaneously remove , CO . As result, Zn‐mtz‐ina exhibits benchmark capacity for (3.01 mmol g −1 IAST selectivity /C (4.7), along low uptake (1.60 among reported similar adsorbents. Dynamic breakthrough experiments confirm direct production polymer‐grade (>99.9%) /CO (1/33/33/33, v/v/v/v gas mixture high productivity 0.36 under ambient conditions. The underlying separation mechanisms guest–host interactions are elucidated through gas‐loaded single crystal analysis, density functional theory calculations, visualized Hirshfeld surface analysis.

Building Stable Pillar-Layered Metal–Organic Frameworks: Introduction of Unsaturated Bonds for Enhanced Efficiency in C₂H₂/CO₂ Separation

ACS Materials Letters, Год журнала: 2024, Номер 6(9), С. 3925 - 3931

Опубликована: Июль 26, 2024

Pillar-layered structures represent a significant category within MOFs; however, the exploration of their chemical stability and systematic functionalization has been largely neglected. Herein, we fabricated pillar-layered MOF (Zn-LC–C) with fsc topology, utilizing tetradentate carboxylic ligand bipyridine Zn(II) ions via approach. Notably, this topological structure displays markedly superior compared typical MOFs pcu topology. In addition, by introducing unsaturated bonds to modify increase length pillars, three additional (Zn-LN=N, Zn-LC=C, Zn-LC≡C) were obtained. Compared those Zn-LC–C, adsorption capacities for C2H2 other have improved. Strikingly, dynamic uptake Zn-LN=N is as high 53.7 cm3 g–1, separation ratio C2H2/CO2 3.2. These results demonstrate that introduction diazo groups in pillar can enhance C2H2.
