Embodiment 1

[0018] 1) Add 30 milliliters of ethanol with a mass fraction of 95% into a 50 milliliter hydrothermal kettle, and then add 1.74*10 -5 mol (0.625 grams) of polyvinylpyrrolidone (PVP) stirred and dissolved, after adding 5.7*10 -4 mol (0.125 g) of zinc acetate dihydrate stirred solvent, and finally added 1.88*10 -2 mol (0.75 grams) of sodium hydroxide and stirred at room temperature for 20 minutes;

[0019] 2) After sealing the hydrothermal kettle, place it in an oven, raise the temperature to 100°C, and keep it warm for 1 hour;

[0020] 3) After the reaction is completed, cool the hydrothermal kettle to room temperature naturally in an oven, open the reaction kettle, open the hydrothermal kettle and pour out the upper layer solution, and keep the precipitated product;

[0021] 4) Wash the product with deionized water and ethanol, and collect the precipitate by centrifugal sedimentation after being dispersed by ultrasonic oscillation. After the precipitate is separated by filtr...

Abstract

A solvothermal synthesis method of nanometer zinc oxide is provided. According to the method, zinc acetate dihydrate is adopted as a raw material, sodium hydroxide is adopted as a basifier and polyvinylpyrrolidone is adopted as an additive. The method includes steps of: adding ethanol into a hydrothermal kettle until the filling degree is 0.6; adding the additive that is the polyvinylpyrrolidone, the raw material that is the zinc acetate dihydrate and the basifier that is the sodium hydroxide in to the solution; stirring for 20-40 min; sealing the hydrothermal kettle; putting the hydrothermal kettle into a baking oven; heating to 50-200 DEG C; maintaining the temperature for 0.5-3 h; naturally cooling; subjecting the obtained product to centrifugation; washing with deionized water and ethanol; and drying to obtain a nanometer zinc oxide product with different morphologies.

Description

technical field [0001] The invention belongs to the field of synthesis and application of nanometer materials, and in particular relates to a method for solvothermally synthesizing nanometer zinc oxide. Background technique [0002] Nano-zinc oxide (ZnO) has at least one dimension below hundreds of nanometers. It is a new type of high-function inorganic fine chemical, which exhibits properties such as non-migration, piezoelectricity, absorption and scattering of ultraviolet and visible light due to its small size. It can be applied to synthetic rubber vulcanization activators, foaming agent additives, high-efficiency photocatalysts, varistors, ultraviolet shielding materials, magnetic materials, etc. Many fields. [0003] Liquid phase chemical synthesis mainly includes solvothermal method, sol-gel method, co-precipitation method and microemulsion method. The sol-gel method, co-precipitation method and microemulsion method have the following problems: (1) the reaction contr...
