The invention relates to a method for preparing
ozone heterogeneous oxidation
solid catalysts, and belongs to the technical field of
environmental protection and chemical catalysts. The method includes carrying out pore expansion and modification on carriers which are attapulgite,
diopside,
sepiolite, baryta
feldspar,
perlite and
albite porous materials by the aid of
lithium hypochlorite and bis (
acetylacetone)
beryllium; adding chlorinated bis-eicosyl dimethyl
ammonium into the carriers and carrying surface activation treatment on the carriers under the effects of ultrasonic
waves; carrying out
hydrothermal reaction on the carriers which are subjected to ultrasonic surface activation,
borax,
potassium sulfate,
tetra-(2, 2, 6, 6-tetramethyl-3, 5-heptadione acid)
cerium (IV), tri-[4, 4, 4-trifluoro-1-(2-
thiophene)-1, 3-butanedione]
europium, tri-(6, 6, 7, 7, 8, 8, 8-heptafluoro-2, 2-dimethyl-3, 5-
octene diketone)
dysprosium (III), tri-[N, N-bis (
trimethylsilane) amine]
erbium rare earth metal organic compounds,
manganese lysine,
ammonium zirconium carbonate, dichlorotetraaminopalladium and tetrachloro
iridium dihydrate in
hydrothermal reaction kettles under the effect of
nitrophenol benzyldimethyl
ammonium bromide which is an emulsifier;
drying reaction products to remove
moisture; burning the reaction products in muffle furnaces at the certain temperatures to obtain the
ozone heterogeneous oxidation
solid catalysts. The chlorinated bis-eicosyl dimethyl ammonium is used as a catalyst. The
borax and the
potassium sulfate are used as composite mineralizers, the
tetra-(2, 2, 6, 6-tetramethyl-3, 5-heptadione acid)
cerium (IV), the tri-[4, 4, 4-trifluoro-1-(2-
thiophene)-1, 3-butanedione]
europium, the tri-(6, 6, 7, 7, 8, 8, 8-heptafluoro-2, 2-dimethyl-3, 5-
octene diketone)
dysprosium (III) and the tri-[N, N-bis (
trimethylsilane) amine]
erbium rare earth metal organic compounds are used as catalytic active auxiliary precursors, the
manganese lysine, the ammonium
zirconium carbonate, the dichlorotetraaminopalladium and the tetrachloro
iridium dihydrate are used as catalytic active central components, the
manganese lysine is a common
transition metal organic compound, and the dichlorotetraaminopalladium and tetrachloro
iridium dihydrate are
precious metal compounds.
