Ozone advanced oxidation catalyst as well as preparation method and application thereof

The invention relates to the technical field of ozone catalytic oxidation, and discloses an ozone advanced oxidation catalyst and a preparation method and application thereof, and the preparation method comprises the following steps: using inorganic acid to carry out surface acid modification on a main carrier; auxiliary carrier slurry prepared from silica sol and aluminum sol is impregnated and loaded on the main carrier, and a composite carrier is obtained through drying and roasting; preparing active slurry from metal oxide, titanium dioxide and manganous nitrate, adjusting the pH value, and treating the precipitate to obtain active powder; and dissolving the active powder, noble metal salt, TiO2 sol, transition metal salt, a binder and a dispersant in water to obtain active coating slurry, and dipping and coating the composite carrier with the active coating slurry to obtain the ozone advanced oxidation catalyst. The method has the beneficial effects that the process is simple, the operability is high, th
