Competitive and Cooperative CO₂-H₂O Adsorption through Humidity Control in a Polyimide Covalent Organic Framework

In order to capture and separate CO2 from the air or flue gas streams through nanoporous adsorbents, the influence of the humidity in these streams has to be taken into account as it hampers the capture process in two main ways: (1) water preferentially binds to CO2 adsorption sites and lowers the overall capacity, and (2) water causes...
