▎ 摘  要

NOVELTY - Vitamin B12 functionalized graphene complex material is prepared by ultrasonically dispersing graphene oxide in water, adding poly(B12-IL) and hydrazine hydrate to graphene oxide solution, heating and centrifuging solution, repeatedly washing solid using distilled water until solution turns colorless and reaches neutral pH, and drying washed product in vacuum. USE - The vitamin B12 functionalized graphene complex material is used for photocatalytically degrading organic halide e.g. 2,2-bis(4-chlorophenyl)-1,1,1-trichloroethane (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of vitamin B12 functionalized graphene complex material for photocatalytically degrading organic halide.
