Embodiment 1

[0015] Take 1.2g ZnSO 4 Dissolve in 30mL distilled water, and dissolve 0.9g urea in 30mL distilled water. Slowly add the aqueous urea solution into the zinc salt solution dropwise under ultrasonic conditions, and continue ultrasonication for 20 minutes after the addition is completed.

[0016] The above reaction solution was placed in a hydrothermal kettle and reacted at 150° C. for 24 hours. The white product was obtained by suction filtration. Wash with distilled water and dry at 300°C.

Embodiment 2

[0018] Take 2.4g ZnSO 4 Dissolve in 30mL of distilled water, and dissolve 0.9g of urea in 15mL of distilled water. Slowly add the aqueous urea solution dropwise to the zinc salt solution under ultrasonic conditions, and continue ultrasonication for 20 minutes after the addition ends.

[0019] The above reaction solution was placed in a hydrothermal kettle and reacted at 150° C. for 24 hours. The white product was obtained by suction filtration. Wash with distilled water and dry at 280°C.

Embodiment 3

[0021] Take 4.45g Zn(NO 3 ) 2 ·6H 2 O was dissolved in 30 mL of distilled water, and 1 g of urea was dissolved in 30 mL of distilled water. Slowly add the aqueous urea solution into the zinc salt solution dropwise under ultrasonic conditions, and continue ultrasonication for 20 minutes after the addition is completed.

[0022] The above reaction solution was placed in a hydrothermal kettle and reacted at 120° C. for 24 hours. The white product was obtained by suction filtration. Wash with distilled water, then dry at 350°C.

Abstract

The invention discloses a nanoscale flower-like zinc oxide preparation method. The flower-like zinc oxide is prepared by ultrasonic-assisted hydrothermal method, and has uniform particle distribution and a nanoscale flower-like structure with uniformly growing slices as petals. The nanoscale flower-like zinc oxide preparation method provided by the invention has the advantages of easily-obtained materials, simple apparatus and process, high efficiency, high speed, high yield, and so on, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to an ultrasonic hydrothermal preparation method of ZnO particles with a nano-flower structure, belonging to the field of nano-material science. Background technique [0002] Due to its special structure, zinc oxide exhibits many special functions in catalysis, optics, magnetism, mechanics, etc. It has important applications in many fields such as biology, medicine and so on. Due to its size between atomic clusters and macroscopic particles, nano-zinc oxide has special properties that many macroscopic materials do not have, such as the volume (small size) effect, surface effect, and macroscopic quantum tunneling effect of nanomaterials. Special properties and uses, it has special functions that ordinary zinc oxide products do not have in terms of magnetism, light, electricity, sensitivity, antibacterial disinfection, ultraviolet shielding, etc. It is a high-function fine inorganic product with broad application prospects. Theref...
