Preparation method of ozone heterogeneous oxidation solid catalyst

Abstract

The invention relates to a preparation method of an ozone heterogeneous oxidation solid catalyst and belongs to the technical field of environment protection and chemical catalysts. The preparation method includes: using activated carbon, carnallite, dolomite, calcite, fluorite and glauberite as the carriers, using lithium hypochlorite and bis(acetylacetone) beryllium to perform pore expansion on the carriers, adding surfactant beta-hydroxyethyl dimethyl dodecyl ammonium sulfate to activate the carriers under ultrasonic action, allowing the carriers to have hydrothermal reaction with compound mineralizer including borax and potassium sulfate, catalytic activity promoter precursors including promethium tricyclopentadienide, tri(2, 2, 6, 6-tetramethyl-3, 5-heptanedionato) gadolinium, terbium acetate hydrate and tri[N, N-bis(trimethyl silane) amine] erbium, and catalytic activity central precursors including cobalt gluconate, cupric glutamate, tetraammine dichloropalladium(II) and diamineplatinum(II) dichloride in a hydrothermal reaction kettle under the effect of an emulsifier chlorinated methyl acryloyloxy ethyl trimethyl ammonium, drying to remove moisture, and burning in a muffle furnace to obtain the ozone heterogeneous oxidation solid catalyst.

Description

technical field

[0001] The invention relates to a preparation method of a solid catalyst for ozone heterogeneous oxidation, which belongs to the technical fields of environmental protection and chemical catalysts. Background technique

[0002] Ozone oxidation technology utilizes the strong oxidation ability of ozone, which can oxidize and decompose many organic pollutants, and is widely used in wastewater treatment. Ozone catalytic oxidation technology is divided into ozone homogeneous catalytic oxidation and ozone heterogeneous catalytic oxidation. Ozone homogeneous catalytic oxidation has catalysts that are difficult to separate, recycle and reuse, and the low utilization rate of ozone leads to high water treatment operation costs. Ozone heterogeneous catalytic oxidation technology has the advantages of easy separation and recovery of catalysts and reusable use, high ozone utilization rate, and high removal rate of organic pollutants, which reduces water treatment.
