Concept shows promise as a way to sidestep the energy penalties of numerous industrial separations

Scientists have developed membranes that separate carbon dioxide from nitrogen. The membranes feature porous graphene decorated with polymers and use interactions between the polymers and carbon dioxide to create a system that can selectively filter carbon dioxide out of flue gas.
