Abstract
An agent for reducing graphene oxide and a method for preparing reduced graphene oxide or graphene are provided. An agent for reducing graphene oxide include a mixture of a reducing agent containing a halogen element with trifluoroacetic acid (CF3COOH).
Claims16
A method of preparing reduced graphene oxide, comprising:
- reacting graphene oxide with an agent for reducing graphene oxide,
- wherein the agent for reducing graphene oxide includes a mixture of a reducing agent containing a halogen element with trifluoroacetic acid (CF3COOH).
A method of producing graphene, the method comprising:
- reducing graphene oxide in a presence of a reducing agent including a halogen element and a solvent, the solvent including an acidic compound that is a weaker acid than the reducing agent.
