Abstract
A method of preparing graphene from coal can include thermally processing raw coal and, after the coal has been at least partially cooled from thermal processing, forming reduced graphene oxide from the coal.
Claims21
A method of producing graphene from coal, the method comprising:
- thermally processing coal at a temperature of at least about 300° F.;
- and
- after the coal has been at least partially cooled from thermal processing, forming reduced graphene oxide from the coal.
A method of producing synthetic graphene, comprising:
- beneficiating an amount of coal including one or more impurity atoms to remove a predetermined amount of the one or more impurity atoms therefrom;
- processing the beneficiated amount of coal to produce an amount of pitch from at least some of the amount of coal;
- and
- treating at least some of the amount of pitch to produce the synthetic graphene;
- wherein the synthetic graphene includes a desired amount of the one or more impurity atoms.
2 more elements
The method of claim 11, wherein the amount of pitch includes mesophase pitch.
A method of producing synthetic graphene, comprising:
- thermally processing an amount of coal to achieve a predetermined concentration of one or more impurity atoms in the amount of coal;
- oxidizing at least some of the amount of coal to form a coal oxide including a predetermined concentration of one or more impurity atoms;
- processing the coal oxide to form reduced graphene oxide including a predetermined concentration of one or more impurity atoms.
A synthetic graphene formed from an amount coal, comprising:
- a predetermined amount of dopant atoms, the dopant atoms derived from the amount of coal.
