Abstract

A filter and a poly-oxygenated aluminum hydroxide material comprising a clathrate containing oxygen gas molecules. The poly-oxygenated aluminum hydroxide material removes NOx from an effluent gas, such as gas emitted from an internal combustion engine. The NOx is held in stasis over a range of temperatures, and may be collected.

Claims

1. A device, comprising:

a filter; and

a poly-oxygenated aluminum hydroxide material comprising a clathrate containing oxygen gas molecules disposed in the filter.

2. The device as specified in claim 1, wherein the filter is a cartridge.

3. The device as specified in claim 1, wherein the poly-oxygenated aluminum hydroxide material is configured to receive an effluent gas.

4. The device as specified in claim 3, wherein the filter has an input configured to receive the effluent gas from an internal combustion engine.

5. The device as specified in claim 1, wherein the poly-oxygenated aluminum hydroxide material is configured to hold the NOx in stasis.

6. The device as specified in claim 5, wherein the poly-oxygenated aluminum hydroxide material is configured to hold the NOx in stasis over a temperature range from −

25 degrees C. to 1200 degrees C.

7. The device as specified in claim 1, wherein the poly-oxygenated aluminum hydroxide material is configured to collect the NOx.

8. The device as specified in claim 1, wherein the poly-oxygenated aluminum hydroxide material is configured to absorb the NOx.

9. The device as specified in claim 7, wherein collected NOx is removable from the filter.

10. The device as specified in claim 1, wherein the filter has a membrane.

11. A method, comprising:

removing NOx from an effluent gas using a poly-oxygenated aluminum hydroxide material comprising a clathrate containing oxygen gas molecules.

12. The method as specified in claim 11, further comprising using a cartridge including the poly-oxygenated aluminum hydroxide material.

13. The method as specified in claim 11, further comprising passing the effluent gas through the poly-oxygenated aluminum hydroxide material.

14. The method as specified in claim 13, wherein the poly-oxygenated aluminum hydroxide material holds the NOx in stasis.

15. The method as specified in claim 14, wherein the NOx is held in stasis over a range of temperatures.

16. The method as specified in claim 11, wherein the NOx is removed from the poly-oxygenated aluminum hydroxide material.

17. The method as specified in claim 16, wherein the removed NOx is collected.

18. The method as specified in claim 11, wherein the poly-oxygenated aluminum hydroxide material absorbs the NOx.

19. The method as specified in claim 11, wherein the effluent gas is received from an engine.

20. The method as specified in claim 19, wherein the effluent gas is received from an internal combustion engine.
