▎ 摘　　要

NOVELTY - A heterophasic Fenton photocatalyst comprises mesoporous carrier having mesoporous surface which is goethite-modified graphene composite. USE - A heterophasic Fenton photocatalyst for degrading organic pollutants e.g. phenol or quinoline in water (all claimed). ADVANTAGE - The photocatalyst can rapidly and efficiently remove organic pollutant in water, particularly phenol and nitrogen-containing heterocyclic ring, and has broad pH range and repeatable practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of heterophasic Fenton photocatalyst which involves preparing graphene oxide supported on mesoporous carrier by graphene oxide dielectric carrier surface modification and reducing graphene oxide to graphene using bivalent iron salt while oxidizing bivalent iron salt to goethite (a-FeOOH) on surface of graphene.
