CO 2 capture from humid flue gases and humid atmosphere using a microporous coppersilicate

Grabbing CO 2 from wet gas streams It is a challenge to extract CO 2 from typical gas streams, such as the flue gas from a power plant. This is because any water in the stream tends to prevent CO 2 absorption and may also degrade the absorbing material. Datta et al. developed a microporous copper silicate that avoids these problems. Most other materials have sites that absorb both water and CO 2 at the same sites, and in that fight, the water tends to win. Although their material still absorbs water, it has separate sites for the CO 2 absorption. It also shows good stability despite the absorbed water and can be reused. Science , this issue p. 302
