Nanowerk  October 24, 2024 The development of a durable material with high capacity, fast kinetics and low regeneration temperature for CO2 capture, especially from the intricate and dynamic atmosphere, is still lacking. An international team of researchers (USA – University of California, Saudi Arabia, Germany) synthesized a porous, crystalline covalent organic framework (COF) with olefin linkages structurally characterized and post-synthetically modified by the covalent attachment of amine initiators for producing polyamines within the pores. The COF could capture CO2 from open air with a capacity of 0.96 mmol g–1 under dry conditions and 2.05 mmol g–1 under 50% relative humidity, both from 400 ppm CO2. […]
