The invention relates to a wet oxidation catalyst as well as a preparation method and application thereof. The catalyst comprises a carrier and a metal oxide active component, the metal component in the metal oxide comprises Mo, Fe and Co, and the relative ratio (Co0. 7Fe0. 3) (MoO4)/MoO3 of the oxidation state crystal phase particle size of the catalyst is greater than or equal to 3.50. When the catalyst is used for treating organic wastewater, the COD removal rate is high. 本发明涉及一种湿式氧化催化剂及其制备方法和应用。该催化剂包括载体和金属氧化物活性组分，所述金属氧化物中的金属组分包括Mo、Fe和Co，其中催化剂氧化态晶相粒径相对比值(Co0.7Fe0.3)(MoO4)/MoO3大于或等于3.50。利用本发明催化剂处理有机废水时，COD去除率高。
