The efficient separation of C2 hydrocarbons (C 2 H 6, C 2 H 4, and C 2 H 2 ) represents a critical challenge in the chemical industry. Developing adsorbents that are capable of achieving efficient one-step separation of ternary C2 hydrocarbons remains a significant hurdle. Herein, we report a Y-based metal–organic framework (MOF), Y(BTAC) (denoted as HIAM-319, H 3 BTAC = 3,3′,3′’-(1,3,5-benzenetriyl)trisacrylic acid, featuring one-dimensional (1D) channels. HIAM-319 exhibited robust structure and preferential adsorption of C 2 H 2 and C 2 H 6 over C 2 H 4 . Dynamic breakthrough experiments further validated its separation capability for C2 hydrocarbons.
