Abstract

The invention provides a method for preparing an Mg-Ti-ZrO2 catalytic material and relates to the technical field of novel nano catalytic materials. ZrOCl2.8H2O, Cl9H42BrN, MgCl2.6H2O and TiCl3 are weighed and placed in a beaker; diluted ammonia water is poured into the beaker, a few drops of anhydrous ethanol are added dropwise, and diluted ammonia water is added dropwise till the pH value of the solution is about 8; the beaker is wrapped with a preservative film, and stirring is carried out for two hours; the solution is poured into a reaction kettle and placed into an oven for hydrothermal reaction; a reaction product is washed through anhydrous ethanol, then subjected to suction filtration and repeatedly washed; the product is placed in a crucible and placed in the oven for drying again; the taken-out product is ground through a mortar, and the Mg-Ti-ZrO2 catalytic material is obtained. The material has the advantages of being high in photocatalytic activity, good in heat stability, high in powder dispersity, good in particle compactness, uniform in particle size distribution and the like, and can be 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 kind of Mg-Ti-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 inactiv...
