Oxidation of graphene via a simplified Hummers’ method for graphene-diamine colloid production
Graphene oxide was prepared by oxidizing the graphene via a simplified Hummers’ method, where it had involved the oxidization of the ultrasonically exfoliated water-dispersible graphene in a H2SO4/HNO3 mixture and the neutralization effect of NaOH, but without the presence of the KMnO4 oxidation age...
