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.

Carbon capture and storage remains one of the most promising strategies to limit the impact of carbon emissions. Some industrial plants already capture carbon dioxide using amine sorbents, where heating regenerates the amines and removes the carbon dioxide – but this process is energy intensive.
