Problems solved by technology

Although the above documents are induced by adding surfactants to assemble nano-zinc oxides with different shapes, the existence of surfactants is not conducive to the cleaning of the product, and at the same time increases the manufacturing cost, and the waste liquid will cause certain pollution to the environment. Good for mass production

Embodiment 1

[0015] 1mmolZn(NO 3 ) 2 ·6H 2 O is put into the autoclave of the polytetrafluoroethylene liner that absolute ethanol is housed, and is sealed. Then put the autoclave containing the reaction reagents into an oven and add heat to 180° C., and keep the temperature constant for 2 hours. The obtained product was separated by centrifugation, washed several times with deionized water, and then placed in a vacuum drying oven at 25° C. for 12 hours to obtain rose-like nano-zinc oxide.

Embodiment 2

[0017] After maintaining the reaction in an oven at 180° C. for 4 hours, it was naturally cooled to room temperature, and the others were the same as above.

Embodiment 3

[0019] After maintaining the reaction in an oven at 180° C. for 6 hours, it was naturally cooled to room temperature, and the others were the same as above.

Abstract

The invention provides rosette nanometer zinc oxide and a preparation method thereof. Zn(NO3) question mark 6H2O is added into absolute ethyl alcohol solution to obtain reaction mixture; then the reaction mixture is injected into a high pressure reaction kettle with an inside lining polyfluortetraethylene liner and sealed; the reaction kettle which has reaction mixture is heated to 180 DEG C, andthe temperature is kept for 2 to 10 hours; after the kettle is naturally cooled to room temperature, the obtained products are centrifugalized and washed with deionized water, and then put into a vacuum drying cabinet for drying for 12 hours at the temperature of 25 DEG C; finally the rosette nanometer zinc oxide is obtained. The invention adopts more accessible absolute ethyl alcohol with nontoxic and low price as revulsant which simultaneously plays the function of scattering so as to reduce agglomeration. The single and uniform rosette nanometer zinc oxide is obtained by the method, which adds a new member to nanometer zinc oxide family; in addition, the rosette nanometer zinc oxide has bionics structure and gives a new thought to bionics intelligent nanophase materials.

Description

(1) Technical field [0001] The invention relates to a zinc oxide with a specific shape and a preparation method thereof, in particular to the preparation of a rose-like nanometer zinc oxide. The invention belongs to the technical field of preparation of inorganic nano functional materials. (2) Background technology [0002] Nano-zinc oxide is a new multi-functional inorganic material. Due to the miniaturization of grains, its surface electronic structure and crystal structure change, resulting in surface effects, volume effects, quantum size effects and macroscopic effects that macroscopic objects do not have. Tunnel effect and high transparency, high dispersion and other characteristics. In recent years, it has been found that it exhibits many special functions in catalysis, optics, magnetism, mechanics, etc., making it have important application value in many fields such as ceramics, chemical industry, electronics, optics, biology, medicine, etc. Specificity and use of c...
