Incorporation of multiple supramolecular binding sites into a robust MOF for benchmark one-step ethylene purification.

ABSTRACT: One-step adsorption separation of C₂H₄ from ternary C₂ hydrocarbon mixtures remains an important and challenging goal for petrochemical industry. Current physisorbents either suffer from unsatisfied separation performance, poor stability, or are difficult to scale up. Herein, we report a strategy of constructing multiple supramolecular binding sites in a robust and scalable MOF (Al-PyDC) for highly efficient one-step C₂H₄ purification from ternary mixtures. Owing to suitable pore confinement with multiple supramolecular binding sites, Al-PyDC exhibits one of the highest C₂H₂ and C₂H₆ uptakes and selectivities over C₂H₄ at ambient conditions. The gas binding sites have be
