Selectively recover CO with this soft nano-porous material

Professor Susumu Kitagawa’s group at Kyoto University (Kyoto, www.sbchem.kyoto-u.ac.jp/kitagawa-lab/index-e.html) has developed a new soft nanoporous material that selectively adsorbs carbon monoxide from gas mixtures. The researchers believe their achievement will enable the separation and recycling of CO from the emissions…
