▎ 摘  要

NOVELTY - Preparation of manganese oxide-metal-organic framework-graphene composite material involves dissolving manganese chloride tetrahydrate and benzoic acid in mixture of water and N,N-dimethylformamide, hydrothermally reacting at 100-160 degrees C, finishing the reaction to obtain manganese-metal-organic framework crystal material, adding the manganese-metal-organic framework crystal material to graphene dispersion, uniformly dispersing to obtain mixed solution, mixing the mixed solution with aqueous oxidizing agent solution at 20-60 degrees C and reacting. USE - The method is useful for preparation of manganese oxide-metal-organic framework-graphene composite material, which is useful for removing formaldehyde (all claimed). ADVANTAGE - The method enables simple, economical and energy-efficient preparation of manganese oxide-metal-organic framework-graphene composite material with high yield and specific surface area. The manganese oxide-metal-organic framework-graphene composite material does not contain noble metal, is rich in surface-adsorbed oxygen species, and can quickly and effectively degrade low concentration formaldehyde at room temperature.
