Abstract
The invention discloses a green reduction method for graphene oxide. The method comprises a step of reducing graphene oxide with tea polyphenol as a reducing agent so as to obtain graphene. According to the invention, since tea polyphenol is used as the reducing agent, reductibility of a phenolic hydroxyl group is utilized for reduction of graphene oxide and tea polyphenol carries out surface non-covalent modification on the obtained graphene; and due to usage of tea polyphenol as the reducing agent, the method is nontoxic, green and environment-friendly and can realize volume production.
