Abstract:
Capturing CO 2 from humid flue gases and atmosphere with porous materials remains costly because prior dehydration of the gases is required. A large number of microporous materials with physical adsorption capacity have been developed as CO 2 -capturing materials. However, most of them suffer from CO 2 sorption capacity reduction or structure decomposition that is caused by co-adsorbed H 2 O when exposed to humid flue gases and atmosphere. We report a highly stable microporous coppersilicate. It has H 2 O-specific and CO 2 -specific adsorption sites but does not have H 2 O/CO 2 -sharing sites. Therefore, it readily adsorbs both H 2 O and CO 2 from the humid flue gases and atmosphere, but the adsorbing H 2 O does not interfere with the adsorption of CO 2 . It is also highly stable after adsorption of H 2 O and CO 2 because it was synthesized hydrothermally.
