▎ 摘　　要

NOVELTY - visible light-Fenton catalyst comprises sodium bismuthate iron-graphene, where the content of sodium bismuthate iron (FexNayBiO3) is 90-99.5 %mass, and x is 2 divide by 7, y is 1 divide by 7, and the content of graphene is 0.5-10 %mass. USE - The visible light-Fenton catalyst is useful for removing nonylphenol (claimed). ADVANTAGE - The visible light-Fenton catalyst has enhanced nonylphenol (NP) adsorption, affinity of the catalyst and substrate by hydrophobic interaction, interface response capability, excellent electronic transmission performance, improves ability of oxidative degradation of NP, and promotes separation and transfer of photogenerated holes and electrons at out-of-phase interface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing visible light-Fenton catalyst, which involves using sodium bismuth as base catalyst and coating with iron to enhance catalytic performance, loading sodium bismuth iron on micron graded graphene, and performing thermal reduction process.
