An ionic ultramicroporous polymer with engineered nanopores enables enhanced acetylene/carbon dioxide separation

A nanopore engineering approach enhances acetylene (C2H2) over carbon dioxide (CO2) selectivity in ionic ultramicroporous polymers (IUPs), an understudied class of sorbents. Extending the cationic arm of a prototypical IUP nearly doubles its C2H2/CO2 selectivity from 4.9 to 8.5 (at 298 K, 1 bar), underpinned by further observations from dynamic separation experiments and bespoke computational insights.

Abstract

A nanopore engineering approach enhances acetylene (C2H2) over carbon dioxide (CO2) selectivity in ionic ultramicroporous polymers (IUPs), an understudied class of sorbents. Extending the cationic arm of a prototypical IUP nearly doubles its C2H2/CO2 selectivity from 4.9 to 8.5 (at 298 K, 1 bar), underpinned by further observations from dynamic separation experiments and bespoke computational insights.
