Abstract

A new strategy is successfully applied to "old" acetyl compounds. A free-standing, porous, N-doped carbonaceous membrane is facilely prepared from the thermal treatment of a pyrrole-ring-containing polymeric membrane based on the superacid-catalyzed copolymerization of acetyl monomers. An exceptional ideal CO2 /N2 permselectivity of 43.2 is achieved with a good CO2 permeability of 1149.3 Barrer, exceeding the recent upper bound for CO2 /N2 .

Keywords: CO2 separation; N-doped membrane; trimerization of acetyl groups.
