One‐step separation of C2H4 from ternary gas mixtures containing acetylene (C2H2), ethylene (C2H4), and carbon dioxide (CO2) represents a great challenge in chemical industry. Herein, we report the electro‐field alignment in a novel anion‐pillared MOF (SIFSIX‐TEPE‐Cu) for benchmark C2H4 separation from C2H2/CO2/C2H4 gas mixtures. The semi‐cage cavities featuring capped facets generated negative potentials...
Engineering pore environments exhibit great potential in improving gas adsorption and separation performances but require specific means for acetylene/carbon dioxide (C2H2/CO2) separation due to their identical dynamic diameters and similar properties. Herein, a novel sulfate‐pillared MOF adsorbent (SOFOUR‐TEPE‐Zn) using 1,1,2,2‐tetra(pyridin‐4‐yl) ethene (TEPE) ligand with dense electronegative pore...
