Abstract

The embodiments of the present disclosure relate to a method and compounds for generating plasma. The method comprises exposing a carbon nanomaterial to a field of microwave radiation. Where the carbon nanomaterial is produced by molten carbonate electrolytic splitting of carbon dioxide.

Claims (19)

1 . A method for generating and using plasma, the method comprising steps of:

(a) generating a field of microwave radiation;

(b) exposing a carbanogel to the field of microwave radiation for generating the plasma, wherein the carbanogel comprises a carbonate electrolyte and a carbon nanomaterial; and

(c) directing the generated plasma at a material for use in cleaning, purifying, disinfecting, healing, etching, modifying, toughening, polishing, promoting flow in, decelerating, or activating the material, or any combination thereof.

2 . The method of claim 1 , wherein the carbon nanomaterial is a graphitic carbon nanomaterial.

3 . The method of claim 1 , wherein the carbon nanomaterial comprises graphene, a carbon nanotube (CNT), a carbon nanofiber (CNF), a thin-walled CNT, a carbon nano-bamboo, a nano-pearl, a nano-tree, a conical CNF, a metal coated Ni-coated CNT, a nano-flower, a nano-dragon, a nano-rod, a nano-belt, a nano-onion, a hollow nano-onion, a nano-scaffold, a nano-platelet and nano-helices.

4 . The method of claim 1 , further comprising a step of providing the carbon nanomaterial as a product of an electrolysis process that splits carbon dioxide.

5 . The method of claim 4 , further comprising a step of introducing a dopant to the electrolysis process for making a doped carbon nanomaterial.

6 . The method of claim 4 , further comprising a step of introducing a magnetic additive component to the electrolysis process for making a magnetic carbon nanomaterial.

7 . The method of claim 1 , further comprising a step of directing the generated plasma at a cell.

8 . The method of claim 1 , further comprising a step of directing the generated plasma for making a plasma shield or a heat shield, an electromagnetic shield, a drag shield or any combination thereof.

9 . The method of claim 1 , further comprising a step of directing the generated plasma for accelerating, trapping, and controlling a flow of ions, a flow of particles, or any combination thereof.

10 . The method of claim 1 , further comprising a step of directing the generated plasma for chemically reducing a gas.

11 . The method of claim 1 , wherein the plasma comprises excited carbon.

12 . The method of claim 1 , wherein the plasma comprises excited components of glass, borosilicate glass, alumina, sodium chloride, basalt, or any combination thereof.

13 . The method of claim 1 , wherein the plasma comprises excited sodium, excited chlorine, excited silicon, excited copper, excited cesium, or any combination thereof.

14 . The method of claim 1 , wherein the plasma comprises a gas.

15 . The method of claim 1 , wherein the plasma comprises a cold plasma, a warm plasma or any combination thereof.

16 . The method of claim 1 , wherein the plasma does not generate any exotic species.
