▎ 摘  要

NOVELTY - Preparing catalyst comprises mixing the graphene oxide solution and trimesic acid solution under stirring condition, adding a soluble transition metal salt solution, continuously stirring and mixing, centrifugally separating, washing and drying to obtain precipitate. USE - The catalyst is useful for removing trace pollutant in sewage (claimed). ADVANTAGE - The catalyst has high catalytic activity, long service life and not easy to cause secondary pollution. The method is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for ozone catalytic oxidation removes trace pollutants from sewage comprising catalyst.
