1. An absorbent structure for CO2 capture comprising:

  • a honeycomb substrate having a plurality of partition walls extending in an axial direction from an inlet end to an outlet end thereby forming a plurality of flow channels, wherein the honeycomb substrate comprises a powder component and a binder that are solidified; and

    a functional mer group dispersed throughout the powder component of the partition walls of the honeycomb substrate, wherein the functional mer group is positioned in and on the partition walls such that, when a gas stream containing CO2 flows in the flow channels from the inlet end to the outlet end, the functional mer group absorbs the CO2 by forming a coordinated bond that forms carbonate, bicarbonate, carbamates, or another coordinated or ionic compound with the CO2.
