Abstract：
 The present invention belongs to the field of water processing technology and environment protecting functional material. The RE CeO2 supported wet oxidizing catalyst has RE CeO2 as carrier and noble metal M or noble metal oxide MOx as the active component, with the loaded noble metal amount being 1-3 wt%. The preparation process includes the following steps: preparing CeO2 carrier with Ce salt and alkali matter as material and through co-precipitation; soaking the CeO2 carrier is noble metal salt solution to load noble metal in 1-3 wt%; and drying and roasting to reduce to obtain the wet oxidizing MOx/CeO2 or M/CeO2 catalyst. The MOx/CeO2 or M/CeO2 catalyst has reduced operation condition of wet oxidation to degrade high concentration hard-to-degrade organic matter, can raise the organic matter deeply oxidizing effect and is favorable to catalytic wet oxidation.
