Abstract

The present invention relates to a novel graphene oxide reducing agent and a method for manufacturing a reduced graphene oxide from graphene oxide using same. More particularly, in the present invention, the reduced graphene oxide is manufactured by reducing a graphene oxide using a reducing agent containing a halogen element, and is applicable as an electric conductor, a semiconductor, and an insulator in various fields.

Claims
