▎ 摘  要

NOVELTY - Preparing vitamin B12 and ruthenium complex bifunctionalized graphene photocatalytic material, comprises (i) ultrasonically dispersing graphene oxide in water, adding hydrazine hydrate, refluxing, and centrifuging to obtain reduced graphene oxide, and (ii) ultrasonically dispersing reduced graphene oxide into water, adding copolymer poly(B12-IL-Ru) into the reduced graphene oxide aqueous dispersion, stirring, centrifuging, washing with water until the supernatant is colorless, and vacuum drying to obtain final product. USE - The photocatalytic material is useful as photocatalyst in photocatalytic degradation of organic-halogenated compounds (claimed) and decomposition of photocatalytic organic-halogenated pesticides. ADVANTAGE - The method: utilizes graphene having excellent electrical conductivity and aromatic substrate having adsorption capacity; and improves catalytic efficiency of photocatalytic material. The photocatalytic material is easy to recycle.
