Abstract

A carbonic anhydrase inspired material was developed by incorporating Zn(II) ion exchanged zeolite β into poly(N-vinylimidazole) solution. The hydrophobic zeolite channels were designed to imitate the function of the hydrophobic pocket in carbonic anhydrase. The composite membrane prepared by casting the material on a polysulfone ultrafiltration membrane showed a high CO₂ permeance of 4620 GPU with a high CO₂/N₂ selectivity of 224.
