Provided is a process for producing graphene oxide (GO) product including forming a reaction mixture including graphite-based precursor and an oxidizing effective amount of an oxygenation agent including a complex of hypofluorous acid (HOF) and an organic solvent (HOF.organic solvent) and mixing the reaction mixture for a time sufficient to cause oxidation of the graphite based precursor. Further provided are products including the GO obtainable by the process or graphene products obtainable therefrom, as well as articles of manufacture including the same.
