Privileged zeolitic sites for humid CO2 adsorption: K+ in double eight-membered rings

Abstract

Humid CO2 adsorption in K+-exchanged zeolites featuring double-eight membered ring (D8R) structures results in CO2 outcompeting and desorbing dimeric water under equilibrated conditions, which is not observed for either the H+-form of the same zeolites or larger-pore zeolites.
