Developing porous materials to overcome the trade-off between adsorption capacity and selectivity for C2 H2 /CO2 separation remains a challenge. Herein, we report stable HKUST-1-like MOF (ZJU-50a), featuring large cages decorated with high density of supramolecular binding sites achieve both storage selectivity. ZJU-50a exhibits one highest (192 cm3 g-1 ) concurrently (12) at 298 K 1 bar. Single-crystal X-ray diffraction studies on gas-loaded crystal unveil that incorporated can selectively take up molecule but not CO2 result in Breakthrough experiments validated its performance mixtures, providing recovery 84.2 L kg-1 99.5 % purity. This study suggests novel strategy engineering into MOFs this separation.

Because C2 H4 plays an essential role in the chemical industry, economical and energy-efficient separation of ethylene (C2 ) from ethane H6 is extremely important. With exception energy-intensive cryogenic distillation, there are few one-step methods to obtain polymer-grade (≥99.95 % pure) /C2 mixtures. Here we report a highly stable metal-organic-framework (MOF) FJI-H11-Me(des) (FJI-H=Hong's group Fujian Institute Research on Structure Matter) which features one-dimensional hexagonal nonpolar pore surfaces constructed by aromatic rings alkyl groups. This adsorbs rather than between 273 303 K. Practical breakthrough experiments with containing 1 have shown that can realize acquisition polymer-grade, 99.95 pure under various conditions including different gas flow rates, temperatures relative humidity.
