Abstract
The invention belongs to the technical field of environment protection and chemical catalysts and relates to an ozone heterogeneous oxidation solid catalyst preparation method. The preparation method includes: taking porous mineral materials including activated carbon, carnallite, illite, ulexite, nitratine and dolomite as carriers; subjecting the carriers to lithium hypochlorite and bis(acetylacetone)beryllium broaching modification; adding surfactant dimethylhexadecylethyl ammonium sulfate for surface activation under the action of ultrasonic waves; subjecting the carriers subjected to ultrasonic surface activation to hydrothermal reaction, with a complex mineralizer composed of borax and potassium sulfate, catalytic activity auxiliary agents including samarium acetylacetonate, tri(4,4,4-trifuloro-1-(2-thiophene)-1,3-butanedione)europium, tri(trifluoromethanesulfonimide)ytterbium and lutetium carbonate hydrate rare earth metal compounds and catalytic activity central components including cobalt gluconate, L-aspartic acid molybdenum, gold potassium chloride, tetraammine dichloropalladium transition metals, in a hydrothermal reactor under the action of N-oleoyl-N',N'-diethylethylenediamine hydrochloride serving as an emulsifying agent; drying reaction products to remove moisture, and firing in a muffle furnace at a certain temperature to obtain an ozone heterogeneous oxidation solid catalyst.
