Azo-cops nab CO2 but let N2 go free | Chemistry World - Scientists have developed a new class of porous polymer that can efficiently trap carbon dioxide while actively rejecting nitrogen. The new material, whose key properties rely on the presence of multiple azo (–N=N–) units within the polymer’s chemical structure, is stable at high temperatures and could be used, the researchers say, as a way to scrub power station flue gases of CO2.(10.1038/ncomms2359)
