▎ 摘　　要

NOVELTY - A nano-hybrid photocatalyst comprises reduced graphene oxide, zinc spinel ferrite bonded on graphene oxide, and lanthanum having a double hexagonal close packed lattice structure, combined with at least one of graphene oxide and zinc spinel ferrite. USE - Nano-hybrid photocatalyst is used for decomposition and removal of organic pollutants chosen from rhodamine B, methylene blue, methylene orange, phenol, and 4-chlorophenol, bisphenol A, sulfamethoxazole, and orange G, in water (all claimed). ADVANTAGE - The nano-hybrid photocatalyst is chemically stable compared to the existing photocatalyst and maintains high photocatalytic activity regardless of pH in water and efficiency of removing pollutants even when reused, and has excellent decomposition and removal effect of organic pollutants regardless of type of organic pollutants. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the nano-hybrid photocatalyst, which involves synthesizing (S1) graphene oxide, forming (S2) reduced graphene oxide by adding sodium borohydride to the graphene oxide, synthesizing (S3) zinc spinel ferrite, mixing (S4) the reduced graphene oxide and zinc spinel ferrite, and adding lanthanum; and #decomposition and removal of organic pollutants, which involves injecting the nano-hybrid photocatalyst into water containing the organic pollutants and irradiating visible light, UV light, or ultrasonic waves into water.
