Hummers' method is a chemical process that can be used to generate graphite oxide through the addition of potassium permanganate to a solution of graphite, sodium nitrate, and sulfuric acid. It is commonly used by engineering and lab technicians as a reliable method of producing quantities of graphite oxide.
Why KMnO4 is used in Hummers method?
Concentration of Sulphuric Acid: Concentration of Sulphuric Acid is most important in Hummers method. ... Effect of KMnO4: In this method, KMnO4 acts as Oxidizer, Sulphuric Acid functionalize the Graphite surface to add functional groups in the presence of reagent like KMnO4.
Which of the following is used to reduce graphene oxide in Hummers method?
In this paper, graphite oxide was prepared from natural flake graphite by Hummers' method through liquid oxidization, and the reduced graphene oxide was obtained by chemical reduction of graphene oxide using NH3 H2O aqueous solution and hydrazine hydrate.
