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 purification
diatom,
kyanite,
nitratine,
dolomite, amazonite and
lithium hydroxyapatite porous materials by the aid of
lithium hypochlorite and bis (
acetylacetone)
beryllium; adding chlorinated dodecyl dimethyl hydroxyethyl
ammonium chloride 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, tri (
hexafluoroacetylacetone)
yttrium (III) dihydrate,
samarium acetylacetone, tri-[4, 4, 4-trifluoro-1-(2-
thiophene)-1, 3-butanedione]
europium,
holmium oxalate decahydrate
rare earth metal organic compounds,
vanadium pyruvic acid isonicotinyl
hydrazone,
nickel citrate, cupric glutamate and tetrachloro
iridium dihydrate in
hydrothermal reaction kettles under the effect of N-dimethyl dodecyl-N'-trimethyl-2-hydroxypropyl
ammonium dichloride 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 dodecyl dimethyl hydroxyethyl
ammonium chloride is used as a surfactant. The
borax and the
potassium sulfate are used as composite mineralizers, the tri (
hexafluoroacetylacetone)
yttrium (III) dihydrate, the
samarium acetylacetone, the tri-[4, 4, 4-trifluoro-1-(2-
thiophene)-1, 3-butanedione]
europium and the
holmium oxalate decahydrate
rare earth metal organic compounds are used as catalytic active auxiliary precursors, the
vanadium pyruvic acid isonicotinyl
hydrazone, the
nickel citrate, the cupric glutamate and the tetrachloro
iridium dihydrate are used as catalytic active central components, the
vanadium pyruvic acid isonicotinyl
hydrazone is a common
transition metal organic compound, and the tetrachloro
iridium dihydrate is a
precious metal compound.
