Abstract
Provided herein is a method for preparing graphene-oxide, the method including contacting graphene and at least one oxidant in a solution including at least one acid solvent thereby forming graphene-oxide.
Claims15
A method for preparing graphene-oxide, the method comprising:
- contacting graphene and at least one oxidant in a solution comprising at least one acid solvent at a temperature between 2-25° C. for a period of between 1 minute to 30 minutes, thereby forming graphene-oxide, wherein:
- the graphene is selected from the group consisting of graphene flakes, graphene sheets, fullerenes, graphene nanotubes, graphene nanoscrolls, and graphene nanoribbons;
- and the method does not comprise sonication.
