NOVELTY - Method for preparing two-dimensional high-entropy alloy of graphene involves (a) mixing the surface functionalized graphene with the solvent to form a graphene solution; (b) mixing titanium salt solution, metal salt solution of manganese, cerium salt solution and nickel salt solution with the graphene solution to form turbid liquid; (c) mixing obtained turbid liquid with graphene solution and heating and refluxing; and (c) calcining the solid in the air to obtain an oxidized graphene intercalated twodimensional high-entropy alloy. USE - The method is useful for preparing two-dimensional high-entropy alloy of oxidized graphene which is useful in catalysis and sensing. ADVANTAGE - The method avoids the complex grinding process. The obtained high-entropy alloy material is two-dimensional sheet material, it has a pore structure, the specific surface area is relatively high, and the effect of cocktail is obvious. It improves the application potential of the high-antropy alloy in the fields of catalysis and sensing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an application of the graphene oxide intercalated two-dimensional high-entropy alloy prepared by the preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows the X ray diffraction collection of illustrative plates of gained graphene intercalation high-entropy alloy prepared in method is useful for preparing two-dimensional high-entropy alloy of oxidized graphene (Drawing includes non-English language text).
