Abstract

The invention discloses a preparation method of size-controllable mono-crystalline zinc oxide nano-rods, and belongs to the technical field of synthesis of nano zinc oxide. The technical solution of the preparation method has the key points of: dissolving zinc acetate dihydrate in a mixed solution of acetic acid and diglycol, performing stirring at room temperature until all particles are dissolved to obtain a clarified solution, transferring the clarified solution into a hydrothermal reaction kettle for reaction at 150 DEG C for 6h, washing white precipitates generated after the reaction with deionized water and ethanol in sequence, and then performing vacuum drying at 60 DEG C to prepare a target product namely the mono-crystalline zinc oxide nano-rods. The preparation method is simple and feasible in operation process, and good in repeatability, the size of the synthesized zinc oxide nano-rods is easy to adjust and control, and the zinc oxide nano-rods can be used for mass production; and the prepared zinc oxide nano-rods are in a mono-crystalline form, and are high in crystallinity and uniform in size, thereby having a relatively good application prospect in the field of photoelectric materials.

Description

technical field [0001] The invention belongs to the technical field of synthesis of nano-zinc oxide, and in particular relates to a method for preparing a size-controllable single-crystal zinc oxide nanorod. Background technique [0002] Zinc oxide is a typical metal semiconductor oxide. It has the characteristics of wide band gap, high exciton binding energy, good thermal stability, simple preparation method, various shapes and sizes, and low price. It can be widely used in ceramics, Chemical, optical, electronic and biological fields. Among them, the one-dimensional zinc oxide nanomaterials have a uniform structure, and most of them are single crystals; they have a high specific surface area; the preferred orientation of crystal growth; fewer crystal defects, which is conducive to the directional transmission of electrons; more obvious quantum size effect, It exhibits unique optical, electrical, and thermal properties, which provide a basis for the development of nanoscal...
