Abstract

The physisorption-based separation of CO₂from CO is an energy-efficient yet challenging approach to obtain pure CO. We have applied an intrinsically porous molecular crystal (PMC), assembled from the readily synthesized macrocyclic cyclotetrabenzoin acetate to the problem of CO₂/CO separation. This nanoporous material possesses both kinetic (micropore) and thermodynamic (CO₂-πand CO₂-carbonyl interactions) factors needed for selective CO₂capture. The moderate CO₂-adsorbent interaction allows easy regeneration needed for pressure swing adsorption (PSA). Both trace (1%) and bulk (50%) amounts of CO₂can be removed from CO₂/CO gas mixtures in PSA processes.
