Problems solved by technology

In recent years, in addition to one-dimensional ZnO nanomaterials such as nanowires, nanobelts, and nanorods, the preparation of other specific shapes such as tower-shaped, petal-shaped, disc-shaped, ring-shaped, dandelion-shaped, and rotor-shaped nano-ZnO has been prepared. It has been reported that in 2004, the Yang Deren research group of Zhejiang University used surfactant-assisted hydrothermal synthesis technology to prepare flower-shaped nano-zinc oxide, but the morphology was not uniform and there was agglomeration (Yang Deren et al J.Phys .Chem.B.2004, 108, 3955)

Abstract

The present invention provides the synthesis process of nanometer zinc oxide material. The synthesis process includes the following steps: a. mixing zinc salt and strong alkali in the weight ratio of 1 to 5-20 to prepare transparent solution; b. adding surfactant solution in 5-30 % concentration into the transparent solution at room temperature and through stirring, with the weight ratio between the transparent solution and the surfactant solution being 100 to 3-20; c. heating the mixed solution in sealed reactor to react; and d. cooling the reaction product to room temperature, washing with deionized water or ethanol, and drying at 60-90 deg.c to obtain cosmos 3D nanometer zinc oxide material.

Description

technical field [0001] The invention belongs to the technical field of inorganic chemical industry, and relates to a preparation method of a nanometer material, in particular to a synthesis method of a zinc oxide nanometer material. Background technique [0002] Since the properties of nanomaterials depend on the specific size and shape of nanomaterials, the synthesis of nanostructures with controllable size and shape is the key to controlling their physical and chemical properties. Therefore, the preparation and characterization of nanomaterials with specific shapes and sizes has been receiving much attention. ZnO is an unusual material with excellent chemical properties and has a wide range of applications in optical devices, gas sensors, rubber additives, pigments, varistors, etc. (Wang Zhonglin et al Science 2001, 291, 1947). ZnO with some novel shapes has shown good optical properties and is expected to be used as photoelectric and laser emitting devices. In recent ye...
