▎ 摘 要
NOVELTY - Graphene-UiO-66-amine modified Z-type bismuth vanadate photocatalyst, is claimed. The photocatalyst has decahedral bismuth vanadate particles with octahedral UiO-66-amine particles dispersed on the surface wrapped by graphene; where the graphene-UiO-66-amine modified Z-type bismuth vanadate photocatalyst has a specific surface area of 270-400 m2/g and a pore volume of 0.15-0.20 cm3/g. USE - The graphene-UiO-66-amine modified Z-type bismuth vanadate photocatalyst is useful in visible light degradation of sulfide (claimed). ADVANTAGE - The graphene-UiO-66-amine modified Z-type bismuth vanadate photocatalyst: can degrade and remove sulfides cyclically. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing graphene-UiO-66-amine modified Z-type bismuth vanadate photocatalyst, comprising dissolving graphene in organic solvent for first ice-bath ultrasonic treatment to obtain graphene solution, adding UiO-66-amine and bismuth vanadate into the graphene solution, performing second ice-bath ultrasonication, and washing and drying to obtain final product; and use method of graphene-UiO-66-amine modified Z-type bismuth vanadate photocatalyst, comprising recycling the graphene-UiO-66-amine modified Z-type bismuth vanadate photocatalyst to degrading and removing sulfide, where the total degradation and removal rate of multi-component sulfides is 90%, and the total removal rate of multi-component sulfides is 85% after being recycled for 4 times.
