Abstract[English]
A sorbent for direct air capture of CO2 includes a porous amine-functionalized polymeric material including a rigid crosslinker having one or more proton binding sites configured to bind a hydronium ion under wet conditions of the direct air capture of CO2, the sorbent having an amine efficiency greater than 0.3.[French]
Un sorbant pour la capture directe dans l'air de CO2 comprend un matériau polymère poreux à fonction amine comprenant un agent de réticulation rigide ayant un ou plusieurs sites de liaison de protons configurés pour se lier à un ion hydronium dans des conditions humides de la capture directe dans l'air de CO2, le sorbant ayant une efficacité d'amine supérieure à 0,3.
