<jats:title>Abstract</jats:title> <jats:p>Reduction of graphene oxide is a promising way for scalable production of graphene. The graphene reduced chemically from graphene oxide, however, retains many defects which were formed in the oxidation process, and thus its crystallinity is rather poor. Here, we report an effective reduction method of graphene oxide by radical treatment in solution. Graphene oxide was reduced more effectively by CH3I or BrC2H4Br than by hydrazine, which is a chemical reagent used for conventional reduction of graphene oxide. This radical reduction would facilitate large-scale production of graphene for various applications.</jats:p>
