A Gemini basic ionic liquid and functionalized cellulose nanocrystal-based mixed matrix membrane for CO2/N2 separation

Abstract

Owing to the adverse environmental impact, carbon capture and separation have gained tremendous interest throughout the globe. Herein, a CO₂/N₂ gas separative mixed matrix membrane containing amine functionalized cellulose nanocrystals and a Gemini basic ionic liquid has been developed, which exhibits the highest permeance of 21 033 GPU and moderate selectivity of 21.3.
