Preparation method of zinc oxide nanorod

Abstract

The invention provides a preparation method of a zinc oxide nanorod and relates to an inorganic nanomaterial. The preparation method comprises the following steps of: dissolving zinc salt into water; adding excessive aqueous alkali until white precipitate is completely dissolved; pouring the obtained solution into a polytetrafluoroethylene high-pressure kettle to perform hydrothermal reaction; filtering and washing; generating white precipitate; and drying to obtain zinc oxide nanorod. The prepared product is rod-like zinc oxide, wherein the diameter is about 150 nm and the average length is about 800 nm; the raw material cost is low; the process is simple and convenient to operate; high-temperature sintering is not required; yield is high; and the reaction condition is controllable. In addition, by the low-temperature preparation method, the process applicability of the nano zinc oxide in different fields can be enlarged.

Description

technical field [0001] The invention relates to an inorganic nanometer material, in particular to a preparation method of zinc oxide nanorods. Background technique [0002] Zinc oxide (ZnO), as a multifunctional material, has many excellent properties. With the research and development of nanomaterials in recent years, the finer particle size and the sharp increase in specific surface area make nano-ZnO have surface effects, small size effects and macroscopic quantum tunneling effects. Therefore, nano-ZnO has special properties and new uses that general ZnO does not have in terms of magnetism, electricity, light, chemistry, physics, and sensitivity, and can be widely used in piezoelectric conversion, transparent electrodes, acoustic wave devices, and piezoresistors. , moisture sensitive, gas sensitive sensors, coatings, photocatalysts, and solar cells and many other fields, showing broad application prospects. [0003] In recent years, there have been some relevant patent ...
