Nanopore Engineering in Scalable Metal–Organic Frameworks for C2H4 Purification from Ternary Mixtures
The selective separation of ethylene (C2H4), carbon dioxide (CO2), and acetylene (C2H2) remains a critical challenge owing to their strikingly similar molecular sizes, polarities, and physical properties. Herein, we demonstrate that precise engineering of a sub-nanometric pore environment in metal–organic frameworks...
