Mechanism of Oxidization of Graphite to Graphene Oxide …

The mechanism of oxidizing reaction in the preparation of graphene oxide (GO) by a chemical oxidation method remains unclear. The main oxidant of graphite oxide has not been determined. Here, we show a new mechanism in which Mn2O7, the main oxidant, is heated to decompose oxygen atoms and react with graphite. The whole preparation …
