Abstract

In general, this disclosure describes method of capturing and storing CO2 on a vehicle. The method includes contacting an vehicle exhaust gas with one or more of a first metal organic framework (MOF) composition sufficient to separate CO2 from the exhaust gas, contacting the separated CO2 with one or more of a second MOF composition sufficient to store the CO2 and wherein the one or more first MOF composition comprises one or more SIFSIX-n-M MOF and wherein M is a metal and n is 2 or 3. Embodiments also describe an apparatus or system for capturing and storing CO2 onboard a vehicle.

First claim

What is claimed is:

1. A method of capturing and storing CO 2 on a vehicle, comprising:
contacting an vehicle exhaust gas with a first metal organic framework (MOF) composition, sufficient to separate CO 2 from the exhaust gas;
contacting the separated CO 2 with a second MOF composition, sufficient to store the CO 2 ; and
wherein the first MOF composition comprises one or more SIFSIX-n-M MOFs and wherein M is a metal and n is 2 or 3.

2. The method of claim 1 , wherein the second MOF composition comprises a soc-MOF analogue.

3. The method of claim 1 , wherein the metal comprises zinc or copper.

4. The method of claim 1 , wherein the metal comprises Cu, Zn, Co, Mn, Mo, Cr, Fe, Ca, Ba, Cs, Pb, Pt, Pd, Ru, Rh, or Cd.

5. The method of claim 1 , wherein the first MOF composition comprises bidentate organic ligands.

6. The method of claim 1 , wherein the first MOF composition comprises bidentate N-donor organic ligands.

7. The method of claim 1 , wherein the first MOF composition comprises a SIFSIX-3-Cu metal organic framework.

8. The method of claim 1 , wherein the first MOF composition comprises a SIFSIX-3-Zn metal organic framework.

9. An apparatus for capturing and storing CO 2 on a vehicle, comprising:
a filter component including a first MOF composition, in contact with an exhaust stream of a vehicle, wherein the first MOF composition is configured to separate CO 2 from the exhaust stream; and
a storage component including a second MOF composition, in fluid communication with the filter component, wherein the second MOF composition is configured to store the separated CO 2 ;
wherein the first MOF composition is selected from SIFSIX-M-3, SIFSIX-M-2-i, and combinations thereof; wherein M is a metal.

10. The apparatus of claim 9 , wherein the second MOF composition comprises a soc-MOF analogue.

11. The apparatus of claim 9 , wherein the metal comprises zinc or copper.

12. The apparatus of claim 9 , wherein the metal comprises Cu, Zn, Co, Mn, Mo, Cr, Fe, Ca, Ba, Cs, Pb, Pt, Pd, Ru, Rh, or Cd.

13. The apparatus of claim 9 , wherein the first MOF composition comprises bidentate organic ligands.

14. The apparatus of claim 9 , wherein the first MOF composition comprises bidentate N-donor organic ligands.

15. The apparatus of claim 9 , wherein the first MOF composition comprises SIFSIX-Cu-3.

16. The apparatus of claim 9 , wherein the first MOF composition comprises a SIFSIX-Zn-3.
