Abstract
This invention involves a preparation method for zinc oxide nanorods. In this method, hydrazine hydrate replaces sodium hydroxide or ammonia as an alkaline mineralizer, and zinc oxide nanorods are prepared by hydrothermal synthesis rapidly and simply. Compared with the conventional hydrothermal synthesis method with sodium hydroxide or ammonia as mineralizer, this method can control the size and morphology of zinc oxide by making use of the alkaline hydrazine hydrate and its coordination compound formed with zinc. Zinc oxide nanorods can be prepared quickly in the absence of any other surfactant and complexing agent.

Summary of the invention
The object of the present invention is to provide a kind of preparation method of zinc oxide nano rod, is to utilize hydrazine hydrate to prepare zinc oxide nano rod for the hydro-thermal technology of mineralizer.Overcome traditional water thermal synthesis zinc oxide nano rod and needed problems such as tensio-active agent or complexing agent are assisted, long reaction time.
The step of the technical solution used in the present invention is as follows:
Zinc chloride and 1: 2 in molar ratio~1: 8 ratio of hydrazine hydrate are put into deionized water for stirring, and produce the precipitation of white pulpous state this moment, and promptly hydrazine hydrate and zinc chloride have formed the precipitation of being made up of coordination compound; After the stirring, the above-mentioned solution for preparing is put into autoclave, compactedness is 80~90%, handles 3~48 hours in 120~280 ℃ of temperature ranges, with solution centrifugal, the drying handled well, has just obtained zinc oxide nano rod then.
Realize the synthetic of ZnO nanometer rod under the situation that need not tensio-active agent or complexing agent, the diameter of nanometer rod is about 70 nanometers, and length is 2~4 microns.
The beneficial effect that the present invention has is: traditional zinc oxide nano rod hydro-thermal synthesis process is made alkaline mineralizer with sodium hydroxide or ammoniacal liquor, has long reaction time (being generally more than ten hour to several days) and needs tensio-active agent or shortcoming such as complexing agent (as cetyl trimethylammonium bromide, citric acid and quadrol etc.) is auxiliary.Maximum characteristics of the present invention are to adopt cheap hydrazine hydrate (N
