The invention relates to a preparation method of an
ozone heterogeneous oxidation
solid catalyst, and belongs to the technical field of environmentally-friendly and chemical catalysts. The preparation method comprises the following steps: by taking
perlite,
albite, kaolin, red gold stone, aluminum
hydroxide and celestite as carriers, reaming the carriers with
lithium hypochlorite and bis(
acetylacetone)
beryllium, then adding N-octadecyldimethyl-N'-trimethyl-propyl
ammonia dichloride serving as a surfactant for surface activation treatment under ultrasonic action, putting the carriers into a
hydrothermal reaction kettle for
hydrothermal reaction together with
borax and
potassium sulfate which serve as composite mineralizers, 1,1,1-trifluoroacetylacetone
neodymium, tri(2,2,6,6-tetramethyl-3,5-hepta-diketo acid)
gadolinium, tri(6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-
octene diketone)
dysprosium (III) and
holmium oxalate hydrate which serve as catalytic active auxiliary precursors,
cobalt gluconate,
nickel citrate,
zinc lactate and
potassium dicyanoargentate (I) which serve as catalytic
active center precursors under the action of dodecanoylamidopropyl dimethyl dihydroxypropyl
ammonium chloride serving as an emulsifier,
drying a
reaction product to remove water, and firing the
reaction product in a
muffle furnace, thus obtaining the
ozone heterogeneous oxidation
solid catalyst.
