Insight into the reaction mechanism of graphene oxide with oxidative free radical

  • Xuejiao Zhou

Graphene oxide(GO), as an important derivative of graphene, could be considered as a super aromatic molecule decorated with a range of reactive oxygen-containing groups on its surface, which endows graphene high reactivity with other molecules. In our previous work, we demonstrated that GO sheets were cut into small pieces(graphene quantum dots, GQDs) by oxidative free radicals(hydroxyl radical HO or oxygen radical [O]) under UV irradiation. It is notable that reactions involving free radicals are influenced by reaction conditions pronouncedly. However, researches on details about reactions of GO with free radicals have not been reported thus far. In this work, the effects of different factors on the photo-Fenton reaction of GO were studied. It is demonstrated that the reaction rate is closely related to the concentration of free radicals. It is speculated that through the optimization of reaction conditions, the reaction of graphene with free radicals could carry out efficiently for further applications.
