Breakthrough in capturing 'hot' CO2 from industrial exhaust

Capturing carbon dioxide from the hot industrial exhaust of cement and steel plants requires cooling the exhaust from around 200 C to 60 C so that liquid amines can react with the CO2. Chemists have now created a new type of metal-organic framework that captures CO2 at high temperatures, avoiding the need to expend energy and water to cool the exhaust. The MOF opens up a new field of high-temperature gas capture.
