Abstract

Embodiments of the present disclosure describe a device for removing CO2 comprising a gas flow inlet, a housing including a SIFSIX-3-Cu metal-organic framework (MOF) composition for sorbing and/or desorbing CO2, and a gas flow outlet. Embodiments of the present disclosure describe an anesthetic system comprising one or more regeneratable cartridges for sorbing and/or desorbing CO2, wherein each of the one or more regeneratable cartridge includes a metal-organic framework composition, wherein at least one of the regeneratable cartridges includes a SIFSIX-3-Cu MOF. Embodiments of the present disclosure describe an alkaline fuel cell comprising a catalyst layer including a SIFSIX-3-Cu MOF composition for sorbing and/or desorbing CO2.

First claim

What is claimed is:

1. A device for removing CO 2 from a gas, comprising:
a gas flow inlet;
a housing including a SIFSIX-3-Cu metal-organic framework (MOF) composition for sorbing and/or desorbing CO 2 ; and
a gas flow outlet.

2. The device of claim 1 , wherein the housing further includes one or more SIFSIX-n-M MOF compositions, wherein n is at least 2 and M is a metal other than Cu.

3. The device of claim 2 , wherein the metal is selected from Zn, Co, Mn, Mo, Cr, Fe, Ca, Ba, Cs, Pb, Pt, Pd, Ru, Rh, and Cd.

4. The device of claim 2 , wherein n is 3.

5. The device of claim 2 , wherein at least one of the SIFSIX-n-M MOF compositions includes a bidentate organic ligand.

6. The device of claim 2 , where at least one of the SIFSIX-n-M MOF compositions includes a bidentate N-donor organic ligand.

7. The device of claim 6 , wherein the bidentate N-donor organic ligand includes a cyclic moiety.

8. The device of claim 2 , wherein at least one of the SIFSIX-n-M MOF compositions includes a pyrazine or dipryidilacetylene ligand.

9. The device of claim 2 , wherein at least one of the SIFSIX-n-M MOF compositions is a SIFSIX-3-Zn MOF.
