NOVELTY - Preparation of optical-phase Fenton catalyst involves providing mesoporous carrier, and modifying the surface of mesoporous carrier using iron-graphene composite. USE - Preparation of optical-phase Fenton catalyst (claimed) used for removing organic pollutant e.g. phenol in water. ADVANTAGE - The method provides optical-phase Fenton catalyst having excellent catalytic effect with respect to nitrogen-containing heterocyclic compound. Fenton catalyst effectively reduces the chemical oxygen demand and total organic carbon in water.
