Abstract

The invention relates to the technical field of a novel nanometer catalytic material, particularly to a preparation method of a Zn-Ce-ZrO2 catalytic material. The preparation method comprises the following steps: weighing and taking ZrOCl2.8H2O, C19H42BrN, ZnCl2 and Ce(SO4)2.4H2O, then pouring into a beaker, and adding distilled water; adding a little amount of absolute ethyl alcohol, then dropwise adding aqueous ammonia until the pH value of the solution is 7-8; performing magnetic stirring and ultrasonic uniform mixing; pouring the solution into a reaction kettle, sealing, placing in a drying oven for hydrothermal reaction; washing the obtained reaction product with distilled water and 95% ethyl alcohol for several times, placing the washed reaction product in a crucible, and placing in a drying oven again for drying; taking out the dried reaction product and finely grinding to obtain the Zn-Ce-ZrO2 catalytic material. The Zn-Ce-ZrO2 catalytic material prepared by adopting the preparation method provided by the invention has the advantages of being high in photocatalytic activity, good in heat stability and high in powder dispersibility, and can be perfectly applied to the field of catalytic materials.

Description

technical field [0001] The invention relates to the technical field of novel nanocatalytic materials, in particular to a Zn-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, with high m...
