▎ 摘　　要

NOVELTY - Non-homogeneous Fenton catalyst comprising a mesoporous support formed by graphene doped mesoporous support complex, whose surface is modified by hematite, is new. USE - The catalyst is useful for degrading organic pollutants, preferably phenol or quinoline in water (all claimed). ADVANTAGE - The catalyst has good catalytic effect, shortens the reaction time and reduces the dissolution of iron ion, and can simultaneously reduce chemical oxygen demand and total organic carbon in water.
