Microbe Reduction and Purification - US20110182772A1

Abstract

A method and device degrade microbes. In one embodiment, the device includes a purification device for producing hydrogen peroxide gas from air. The air comprises water vapor and oxygen. The purification device includes a body comprising an interior, an air inlet, and a gas outlet. The purification device also includes a catalyst. The catalyst is disposed within the interior. The catalyst comprises titanium dioxide. In addition, the purification device includes a light disposed to emit electromagnetic radiation into the catalyst. Moreover, the purification device includes a fan. The fan is disposed to blow air in a direction. The catalyst is disposed at an angle in relation to the direction.

Claims

1. A purification device for producing hydrogen peroxide gas from air, wherein the air comprises water vapor and oxygen, comprising: a body comprising an interior, an air inlet, and a gas outlet; a catalyst, wherein the catalyst is disposed within the interior, and wherein the catalyst comprises titanium dioxide; a light disposed to emit electromagnetic radiation into the catalyst; and a fan, wherein the fan is disposed to blow air in a direction, and wherein the catalyst is disposed at an angle in relation to the direction.


2. The purification device of claim 1, wherein the catalyst comprises a metallic additive.


3. The purification device of claim 2, wherein the metallic additive comprises copper, silver, rhodium, or any combinations thereof.


4. The purification device of claim 1, wherein the catalyst comprises a plurality of hexagonal, walled cells.


5. The purification device of claim 1, wherein the angle is between about 15 degrees and about 75 degrees.


6. The purification device of claim 1, wherein the light comprises a non-ozone producing ultraviolet light.


7. The purification device of claim 1, wherein the light is disposed within the catalyst.


8. The purification device of claim 1, wherein the gas outlet is disposed on an opposing side of the air puri􀂡cation device from the air inlet.


9. The purification device of claim 1, wherein the catalyst is disposed to provide a reaction surface by which the air reacts when exposed to the catalyst and the electromagnetic radiation.


10. The purification device of claim 1, wherein producing the hydrogen peroxide gas does not produce ozone.


11. A method of degrading microbes, comprising:

  • (A) feeding air to a catalyst, wherein the catalyst comprises titanium dioxide, and wherein the air comprises water vapor and oxygen;

  • (B) emitting electromagnetic radiation from a light, wherein the electromagnetic radiation contacts the catalyst;

  • (C) reacting the air in the presence of the catalyst and the electromagnetic radiation to produce hydrogen peroxide gas; and

  • (D) degrading the microbes with the hydrogen peroxide gas.


12. The method of claim 11, wherein the catalyst further comprises copper, silver, rhodium, or any combinations thereof.


13. The method of claim 11, wherein the catalyst comprises a plurality of hexagonal, walled cells.


14. The method of claim 11, further comprising feeding the air to the catalyst with the catalyst disposed at an angle.


15. The method of claim 14, wherein the angle is between about 15 degrees and about 75 degrees.


16. The method of claim 11, wherein the light comprises a non-ozone producing ultraviolet light.


17. The method of claim 11, wherein the light is disposed within the catalyst.


18. The method of claim 11, wherein the production of the hydrogen peroxide gas does not produce ozone.


19. The method of claim 11, wherein the air comprises ambient air.


20. The method of claim 11, wherein the air flows through the catalyst.
