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...
New life for “old” acetyl compounds: CO2‐selective, N‐doped carbonaceous membranes can be facilely prepared via thermal treatment of pyrrole‐ring‐containing polymeric membranes based on the superacid‐catalyzed copolymerization of acetyl monomers. A solution‐based synthesis of these free‐standing membranes with application to CO2 separation is described by Sheng‐Dai, Honglai Liu, Shannon Mahurin and...
