Abstract：
 The invention relates to a kind of rare-earth radical loading-mode catalyst in wet-form oxidation, which belongs to the field of water treatment technique and environment functional material. The invention offers a CeO2 multi-component loading-mode catalyst in the rank of millimicron with the high activity and stability, and its manufacturing method. It can decline the operating condition of the wet form oxidizing reaction, and improve the deep oxidizing effictiveness or the pre-treatment ability of the organic matter in the wastewater. The catalyst of the invention contains CeO2-TiO2 and the noble-metal oxide MOx, and it manufactured with the steps as follows: first, with the stuff of cerium salt and titanium salt, manufacture CeO2-TiO2 by the way of collosol and gelation; then dip the CeO2-TiO2 into the solution of noble-metal salt, and the loaded quantity is 1-3wt%; finally, through dipping, desiccating and roasting, the MOx/CeO2-TiO2 catalyst can be acquired.
