▎ 摘　　要

NOVELTY - Double-metal doped graphene nano material comprises using a two-solvent method to adsorbing transition metal elements and dicyandiamide on the metal organic framework compound, harvesting the precipitate from the mixed solution and drying the precipitate, calcining at a high temperature under an inert atmosphere to obtain a carbonized product, subjecting the obtained carbides sequentially to acid etching, washing and drying, where the metal organic framework compound used as precursor. USE - The double-metal doped graphene nano material is useful in antibacterial, removing formaldehyde and removing tumor operation (claimed). ADVANTAGE - The material: has high catalytic efficiency, hydrogen peroxide utilization rate and social value and clinical application prospect; and catalyzes the hydrogen peroxide to generate strong oxidizing free radical in weak acid and neutral environment.
