The invention is applicable to the technical field of ozone catalysts, and provides an ozone catalyst and a preparation method thereof, the ozone catalyst is composed of an outer layer, a middle layer and an inner layer from outside to inside in sequence; the outer layer comprises the following components: gelatin, aluminum oxide and nano silicon dioxide; the middle layer comprises the following components: carbon nanotubes, graphene, activated carbon and zinc oxide; the inner layer is prepared from the following components: metalloporphyrin, rare earth oxide, plant polysaccharide and nano titanium dioxide; the mass ratio of the outer layer to the middle layer to the inner layer is (1-2): (2-5): (2-3); preferably, the outer layer is prepared from the following components in parts by mass: 3 to 6 parts of gelatin, 0.7 to 1.5 parts of aluminum oxide and 1.1 to 1.7 parts of nano silicon dioxide. Through mutual cooperation of the components and adoption of a three-layer structure, the prepared ozone catalyst not
