Abstract

Single-step ethylene (C₂H₄) production from acetylene (C₂H₂), ethylene (C₂H₄), and ethane (C₂H₆) mixtures was realized via the strategy of a flow channel with recognition corners in MOF NTUniv-64. Both the uptake amounts and the enthalpy of adsorption (Q_st) showed the same order of C₂H₂ > C₂H₆ > C₂H₄. Breakthrough testing also verified the above data and the C₂H₄ purification ability. Grand Canonical Monte Carlo (GCMC) simulations indicated that uneven corners could precisely detain C₂H₂ and C₂H₆, in which the C-H···π interaction distance between C₂H₂ (2.84 Å) and C₂H₆ (3.03 Å) and the framework was shorter than that of C₂H₄ (3.85 Å).
