▎ 摘　　要

NOVELTY - A ternary magnetic composite nanomaterial is layered graphene/graphitic carbon nitride-zinc oxide/iron-coated carbon nanotubes comprising sheet-shaped graphene/graphitic carbon nitride, sheet-shaped zinc oxide and iron-coated carbon nanotubes loaded between zinc oxide and sheet-shaped graphene/graphitic carbon nitride. The graphene/graphitic carbon nitride comprises graphene at the edges of graphitic carbon nitride. USE - Ternary magnetic composite nanomaterial used for degradation of organic pollutants e.g. bisphenol A, phenol, caffeine, and organic dyes in water (claimed). ADVANTAGE - The ternary magnetic composite nanomaterial has expanded light absorption range by introducing graphene, zinc oxide and iron-coated carbon nanotubes into graphitic carbon nitride, and can effectively activate persulfate to degrade bisphenol A in water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the ternary magnetic composite nanomaterial, which involves (1) calcining the carbon and nitrogen source to obtain graphene/graphitic carbon nitride (C3N4-Cg), (2) calcining the zinc source to obtain zinc oxide, (3) mixing the carbon and nitrogen source and the iron source and then calcining to obtain iron-coated carbon nanotubes (CNFe), and (4) compounding graphene/graphitic carbon nitride, zinc oxide and iron-coated carbon nanotubes by ultrasonic immersion method.
