▎ 摘  要

NOVELTY - Preparing composite catalyst comprises loading metal oxide and doped nitrogen element on the carbon base material to obtain the composite catalyst, where the nitrogen-containing precursor doped with nitrogen element is ammonia gas and/or inorganic ammonium salt. USE - The composite catalyst is useful for catalytic ozone oxidation treatment of wastewater (claimed). ADVANTAGE - The method is simple, economical, is suitable for large-scale application and has high efficiency in catalytic ozone oxidation treatment of waste water. The catalyst has long stable service life and wide application prospect, and can not selectively mineralize the organic matter in the waste water into carbon dioxide and water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for composite catalyst.
