Porous materials for C2 H2 /CO2 separation mostly suffer from high regeneration energy, poor stability, or cost that largely dampen their industrial implementation. A desired adsorbent should have an optimal balance between excellent performance, and low cost. We herein report a stable, low-cost, easily scaled-up aluminum MOF (CAU-10-H) highly efficient separation. The suitable pore confinement in CAU-10-H can not only provide multipoint binding interactions with but also enable the dense packing of inside pores. This material exhibits one highest storage densities 392 g L-1 selective adsorption over CO2 at ambient conditions, achieved by enthalpy (27 kJ mol-1 ).

Physical separation of C2H2 from CO2 on metal–organic frameworks (MOFs) has received substantial research interest due to the advantages simplicity, security, and energy efficiency. However, that exhibit very close physical properties makes their exceptionally challenging. Previous work appeared mostly focused introducing open metal sites aims enhance affinity at desired sites, whereas reticular manipulation organic components rarely been investigated. In this work, by reticulating preselected amino hydroxy functionalities into isostructural ultramicroporous chiral MOFs—Ni2(l-asp)2(bpy) (MOF-NH2) Ni2(l-mal)2(bpy) (MOF-OH)—we targeted efficient uptake C2H2/CO2 separation, which outperforms most benchmark materials. Explicitly, MOF-OH adsorbs amount with record storage density 0.81 g mL–1 ambient conditions, even exceeds solid 189 K. addition, gave IAST selectivity 25 toward equimolar mixture C2H2/CO2, is nearly twice higher than MOF-NH2. Notably, adsorption enthalpies for zero converge in both MOFs are remarkably low (17.5 kJ mol–1 16.7 MOF-NH2), our knowledge lowest among rigid sorbents. The efficiencies validated multicycle breakthrough experiments. DFT calculations provide molecular-level insight over adsorption/separation mechanism. Moreover, can survive boiling water least 1 week be easily scaled up kilograms eco-friendly economically, crucial potential industrial implementation.
