▎ 摘　　要

NOVELTY - Synthesis of graphene two-dimensional nickel hydroxide nanomaterial comprises dissolving nickel salt and alkaline reagent in hydrophilic solvent, dissolving hexavalent chromium in solution, with nickel ion at 0.05-1.5 mol/L and hydroxyl ion at 0.2-6 mol/L, mixing at mol ratio of first divalent nickel ion and hydroxyl ion at 1:1-8, condensing and refluxing under microwave, naturally cooling to room temperature, centrifugally separating to obtain nanomaterial, washing with deionized water and absolute ethyl alcohol, and drying into vacuum drying box to obtain nanomaterial. USE - Method of synthesis of graphene two-dimensional nickel hydroxide nanomaterial (claimed). ADVANTAGE - The method has short reaction period, high reaction yield, produces high purity product, and is suitable for industrial production.
