Abstract

The invention relates to the technical field of novel nano catalytic materials, in particular to a preparing method for a Mg-Ti-Ce-ZrO2 catalytic material. The preparing method includes the steps that ZrOCl2.8H2O, C19H42BrN, MgCl2.6H2O, TiCl3 and Ce(SO4)2.4H2O are weighed and put into a beaker; diluent ammonia liquor is poured into the beaker, several drops of absolute ethyl alcohol are added dropwise, and diluent ammonia liquor is added dropwise until the pH value of the solution is about eight; the beaker is wrapped by a preservative film, and the solution is stirred for two hours; the solution is poured into a reaction kettle, and the reaction kettle is put into a drying box to carry out a hydrothermal reaction; a reaction product is washed with absolute ethyl alcohol, then filtered in a suction mode and washed repeatedly; the product is put into a crucible, and the crucible is put into the drying box again to dry the product; the product taken out is ground fine through a mortar to obtain the Mg-Ti-Ce-ZrO2 catalytic material. The Mg-Ti-Ce-ZrO2 catalytic material has the advantages of being high in photocatalytic activity and powder dispersity, good in heat stability and particle compactness, uniform in particle size distribution and capable of being perfectly applied to the field of catalytic materials.

Description

technical field [0001] The invention relates to the technical field of novel nanometer catalytic materials, in particular to a Mg-Ti-Ce-ZrO 2 Preparation method of catalytic material. Background technique [0002] Materials are the material basis for human survival and development, and play an important role in national economic and social development. With the continuous development of electronics and new materials industry, nano ZrO 2 And its composite materials will be widely used, especially in the technical field of catalytic materials, which will inevitably cause a certain research upsurge. [0003] Zirconia (ZrO 2 ) is a relatively important functional and structural material in modern industry and material fields. It has very excellent physical and chemical properties, and its hardness is inferior to diamond. Pure ZrO 2 It is a colorless and odorless crystal, insoluble in water, hydrochloric acid and dilute sulfuric acid. Its chemical properties are inactive, wi...
