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
perlite,
albite, kaolin,
rutile, amazonite and kunzite as carriers; subjecting the carriers to
lithium hypochlorite and bis(
acetylacetone)
beryllium broaching modification; adding surfactant N-octadecyldimethyl-N'-trimethyl-propyl
ammonium chloride 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 agent precursors including 1,1,1-
neodymium trifluoroacetylacetonate, tri(2,2,6,6-tetramethyl-3,5-hydrochelidonic acid)
gadolinium, tri(6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octenyldiketone)
dysprosium (III) and
thulium trifluoromethanesulfonate (III)
rare earth metal organic compounds and catalytic activity central component precursors including normal
transition metal organic compounds namely
cobalt gluconate,
nickel citrate and
zinc lactate and a
precious metal compound namely terpyridyl
ruthenium chloride hexahydrate, in a hydrothermal reactor under the action of dimethylamino
ammonium glycolate chloroacetate palmitate 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.
