Getting CO2under control: This Review highlights the challenges for carbon capture and storage technologies which have been proposed to reduce CO2 emissions from large point sources. The most recent developments in new materials and emerging concepts for CO2 separations by absorption, adsorption, and membranes, amongst other approaches, are discussed, with particular attention on progress in the burgeoning field of metal- organic frameworks (see example). © 2010 Wiley-VCH Verlag GmbH & Co.
