Preparation method of ozone heterogeneous oxidation solid catalyst

The invention relates to a preparation method of an ozone heterogeneous oxidation solid catalyst, and belongs to the technical fields of environment protection and catalysts for chemical industry. The preparation method comprises the following steps of using diatomite, kyanite, talcum, trona, pulverized fuel ash and coal gangue as carriers, expanding pores of the carriers by lithium hypochlorite and bis(acetylacetone)beryllium, and adding a surfactant (monoalkyl ether trimethyl ammonium chloride) for activating treatment under the action of ultrasonic wave; then, performing hydrothermal reaction on the carriers, composite mineralizing agents (borax and potassium sulfate), catalytic activity additive precursors (yttrium tri(hexafluoroacetylacetone) (III) dihydrate, tri(cyclopentadienyl) promethium, tris(4,4,4-trifluoro-1-(2-thienyl)-1,3-butanediono)europium (III), and thulium(III) trifluoromethanesulfonate), and catalytic activity center precursors (pyruvic acid isonicotinyl hydrazone vanadium, cobalt gluconate, catechol ethylenediamine tungsten complex and gold potassium chloride) in a hydrothermal reaction kettle under the action of an emulsifier (oleamide propyl trimethyl methylsulfate ammonia), drying to remove water, and firing in a muffle furnace, so as to obtain the ozone heterogeneous oxidation solid catalyst.
