1. A method of producing a graphene oxide product, the method comprising:
contacting a carbon-containing feedstock with an oxidizing composition comprising aqueous nitric acid to from a reactant slurry wherein the concentration of nitric acid is 50 to 63 wt % in the reactant slurry;
controlling the temperature of the reactant slurry during the contacting step to a temperature between 50 and 90° C.;
in response to the contacting step, oxidizing the carbon-containing feedstock of the reactant slurry to form a graphite oxide slurry; and
processing the graphite oxide slurry into a graphene oxide product.
