Abstract
Methods for converting carbon dioxide (CO2) into graphene are described. The methods include contacting a metal with gaseous carbon dioxide, and irradiating a surface of the metal with at least one laser beam to convert the gaseous carbon dioxide into graphene on the surface of the metal. Systems for converting carbon dioxide into graphene are also described.
Claims25
A method for converting carbon dioxide into graphene, the method comprising:
- providing solid carbon dioxide and a metal in a reaction vessel;
- subliming the solid carbon dioxide to form gaseous carbon dioxide;
- contacting the metal with gaseous carbon dioxide;
- and
- irradiating a surface of the metal with at least one laser beam to locally heat the surface of the metal to a temperature in a range of 400° C. to 900° C. and convert the gaseous carbon dioxide into graphene on the surface of the metal.
2 more elements
A system for converting carbon dioxide into graphene, the system comprising:
- at least one reaction vessel configured to contact a metal with gaseous carbon dioxide, wherein the reaction vessel is further configured to receive solid carbon dioxide, and to sublime the solid carbon dioxide to form the gaseous carbon dioxide;
- and
- at least one laser device configured to irradiate a surface of the metal with a laser beam to locally heat the surface of the metal to a temperature in a range of 400° C. to 900° C. and convert the gaseous carbon dioxide into graphene on the surface of the metal.
