We report a green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation catalyzed with 2,2,6,6-tetramethyl-4-piperidinol. While the sp2-hybridized oxygen functional groups are removed after the reduction, the epoxy and hydroxyl groups are retained in...
