View Patent ↗Embodiments presented herein relate generally to the formation of diamond-like carbon, forms of diamond-like carbon and/or carbon dioxide fixation.
1. A method of producing diamond-like carbon, the method comprising:
providing a volume of gas comprising carbon dioxide; and
performing a non-thermal plasma process on the carbon dioxide to produce diamond-like carbon, wherein the plasma process is performed with an input voltage of 10-200V, a frequency of 50-1000 Hz, and at a temperature of 17-50° C.
2. The method of claim 1 , wherein the volume of gas comprises a polluted volume of gas.
3. The method of claim 2 , wherein the polluted volume of gas is obtained from an exhaust.
4. The method of claim 2 , wherein the polluted volume of gas is an exhaust from burning a fossil fuel.
5. The method of claim 1 , wherein the carbon dioxide within the volume of gas is an undesired pollutant within the volume of gas.
6. The method of claim 1 , wherein the carbon dioxide was not added to the volume of gas from a source of pure carbon dioxide.
7. The method of claim 1 , wherein the non-thermal plasma process does not involve physical vapor deposition, chemical vapor deposition, or electrochemical liquid deposition.
8. The method of claim 1 , wherein the diamond-like carbon is produced on a metal electrode.
9. The method of claim 8 , wherein the metal electrode comprises at least one of silicon, metal alloy, and diamond.
10. A method for fixation of carbon from carbon dioxide gas, the method comprising:
providing a volume of gas comprising carbon dioxide; and
performing a non-thermal plasma process to deposit at least some of the carbon dioxide on an electrode, thereby fixing carbon dioxide.
11. The method of claim 10 , wherein the non-thermal plasma process occurs at atmospheric pressure.
12. The method of claim 10 , wherein the non-thermal plasma process is performed at a temperature of 17 degrees Centigrade to 50 degrees Centigrade.
13. The method of claim 10 , wherein the volume of gas consists essentially of carbon dioxide.
14. The method of claim 10 , wherein the non-thermal plasma process occurs at a temperature of equal to or less than 150 degrees Centigrade.
15. The method of claim 10 , wherein the non-thermal plasma process occurs at a pressure of equal to or higher than 100 Torr.
16. A method for reducing carbon dioxide from a volume of polluted gas, the method comprising:
providing a volume of polluted gas that comprises carbon dioxide;
providing at least one conductive structure; and
removing at least part of the carbon dioxide by depositing the carbon dioxide as diamond-like carbon on the conductive structure, thereby reducing carbon dioxide from the volume of polluted gas.
17. The method of claim 16 , wherein the diamond-like carbon is produced on the conductive structure.
18. The method of claim 16 , wherein the conductive structure has a shape of at least one of mesh, foil, or wire.
19. A diamond-like carbon (DLC) composition comprising:
diamond-like carbon powder and at least one non-thermal plasma processed pollutant.
20. A diamond-like carbon (DLC) coated electrode, the electrode comprising:
at least one conductive electrode;
a diamond-like carbon material deposited on the at least one electrode; and
at least one pollutant deposited on the at least one electrode.
21. The method of claim 20 , wherein the electrode comprises at least one of silicon, metal alloy, and diamond.
22. The composition of claim 20 , wherein the pollutant is at least one of a compound comprising a carbonyl group, a SOx or a NOx.
23. An exhaust system comprising:
an inlet for an exhaust gas;
an outlet for the exhaust gas;
at least one chamber fluidly connected to the inlet and the outlet, wherein the chamber is configured for generating a non-thermal plasma; and
at least one electrode within the chamber by which the non-thermal plasma can be generated.
