▎ 摘  要

NOVELTY - A flower spherical copper-metal organic framework-74-graphene oxide (Cu-MOF-74/GO) visible photocatalyst is prepared by dissolving copper(II) nitrate trihydrate and 2,5-dihydroxyterephthalic acid in mixed solution of N,N-dimethylformamide (DMF) and isopropanol for temporary ultrasonic treatment to obtain precursor solution, adding graphene oxide, ultrasonically dispersing to obtain mixed solution, putting into PTTFE reaction kettle, naturally cooling to room temperature, keeping at 110 degrees C for 18 hours to obtain product, respectively washing by DMF and methanol, drying, and standing under vacuum at 150 degrees C for overnight. The concentration of copper(II) nitrate trihydrate and 2,5-dihydroxyterephthalic acid in mixed solution of DMF and isopropanol is 24.0 g/L and 8.0 g/L, respectively. The molar ratio of copper(II) nitrate trihydrate and 2,5-dihydroxyterephthalic acid is 2:1. USE - The method is used for preparing flower spherical copper-metal organic framework-74-graphene oxide visible photocatalyst used for photocatalytic degradation of organic pollutant (claimed). ADVANTAGE - The method has simple and easy to obtain raw material, has low cost and avoids generation of pollution by-product. The photocatalyst has good dispersion degree and excellent photocatalytic.
