specific Embodiment approach 1

[0007] Specific embodiment one: the preparation method of a kind of spindle structure zinc oxide of this embodiment is carried out according to the following steps: one, preparation concentration is the zinc nitrate aqueous solution of 0.01mol / L~0.1mol / L; Two, under stirring condition, Add the sodium hydroxide aqueous solution with a concentration of 4.5mol / L~5.5mol / L dropwise into the zinc nitrate aqueous solution prepared in step 1 until the pH value of the solution is 9~11 to obtain a mixed solution; 3. Under stirring conditions , the temperature of the mixed solution obtained in step 2 was raised to 73°C-78°C and kept for 10h-24h to obtain the mixture; 4. The mixture obtained in step 3 was washed with deionized water and ethanol in sequence, and then heated at 60°C-90 Drying for 10h-24h at ℃ to obtain a white powder; 5. heat-treat the white powder obtained in step 4 in a sintering furnace at 500℃-700℃ for 1.5h-3h to obtain zinc oxide with a spindle structure.

Abstract

The invention discloses a method for preparing zinc oxide of a spindle-shaped structure, which relates to a method for preparing zinc oxide, and solves the problems that the spindle-shaped zinc oxide synthesized by the existing solvothermal method contains impurity ions which can not be easily separated and the yield of the zinc oxide with the spindle-shaped structure in the zinc oxide product synthesized by the hydrothermal method is low. The method for preparing the zinc oxide with the spindle-shaped structure comprises the following steps: dropwisely adding sodium hydroxide solution to zinc nitrate solution, stirring and keeping at 73-78 DEG C for 10-24 hours, cleaning, drying, and performing heat treatment in a sintering furnace. The method is a green chemical preparation method, no organic solvent or surface active agent is used in the reaction process, the product is the single-crystal zinc oxide of hexagonal wurtzite without impurities, and all the prepared zinc oxide are spindle-shaped. The spindle-shaped nano zinc oxide can be used in the fields of laser devices, sensors and light detectors.

Description

technical field [0001] The invention relates to a preparation method of zinc oxide. Background technique [0002] Zinc oxide materials have a wide range of applications in the fields of catalysis, photoelectricity, gas sensing, magnetism and lithium batteries. ZnO nanomaterials with specific size, shape, dimension and monodispersity can further realize the assembly of materials and construct functional structural systems due to their unique properties. Among them, zinc oxide with a spindle structure can be used in the fields of lasers, sensors and photodetectors due to its novel morphology and excellent optical properties. In the method for preparing zinc oxide with a spindle structure, the existing solvothermal method results in the oxidation of the synthesized spindle structure due to the use of organic solvents or the addition of organic alkoxides such as ethanol or zinc alkoxide (zinc alpha-lipoic acid) Zinc contains impurity ions, which are difficult to purify and inh...
