Abstract
The invention provides a method for preparing zinc oxide nanometer stick array by hydro-thermal method. The first step is that a square analyzing pure zinc plate with a length of 1cm is taken and acetone is used to carry out ultrasonic cleaning on the zinc plate; the second step is that 0.2g OT (aerosol) is arranged into a stainless steel high-pressure reactor the inside of which is provided with a polyfluortetraethylene sleeve, then distilled water is filled till the position which is 0.5 to 0.3cm far from the opening of the sleeve and the OT is led to be completely dissolved into the distilled water; the third step is that the cleaned zinc plate is arranged in the reactor of the second step and then the high-pressure rector is sealed; the fourth step is that the high-pressure reactor is arranged into a temperature controlled oven to rector for 2 to 6 hours at 80 DEG C, then the zinc plate is taken out, washed by alcohol at first, and then washed by the distilled water, and dried in the air, thus obtaining the zinc oxide nanometer stick on the surface of the zinc plate.
Description

(2) background technology
Nano material's structure and pattern have very big influence to the performance and the application of nano material.The nano material of preparing ad hoc structure is significant for the frontier of exploitation nano ZnO.
In numerous nano materials, the nanostructure of zinc oxide has caused general interest.The zinc oxide of nanostructure is owing to having large surface area and good magnetic, light, electrical property enjoys attention, and it is expected in fields such as storage hydrogen device, metal-ionization cell, electric chemical super electric capacity, photocell, biosensor, vapor phase sensor, flat-panel monitors goodish application prospect is arranged.
The preparation method of zinc oxide nano rod comprises hydrolysis decomposition method, high-temperature decomposition, vapor deposition method or the like at present.Compare with the present invention, at present there are shortcomings such as equipment complexity, cost height, temperature of reaction height, efficient are low in these methods of report.Therefore, work out a kind of cheapness, method simple to operate, that prepare the uniform zinc oxide nano rod of pattern has this important meaning.
(3) summary of the invention
The present invention is the method for a kind of simple to operate, good reproducibility, preparation condition gentleness, the uniform hydro-thermal reaction growing nano-rod of product pattern zinc oxide.
The technical solution used in the present invention is:
The first step: getting a length of side is the square analytical pure zinc metal sheet of 1cm, with acetone zinc metal sheet is carried out ultrasonic cleaning;
Second step: 0.2gOT as in the interior stainless steel autoclave that tetrafluoroethylene cover arranged, is injected distilled water,, make OT be dissolved in the distilled water fully until the position of distance running-on 0.5～0.3cm;
The 3rd step: cleaned zinc metal sheet is put into the reactor in second step, and autoclave is sealed;
The 4th step: autoclave is put into temperature control oven, and reaction is after 2～6 hours down at 80 ℃, and the taking-up zinc metal sheet is used earlier alcohol wash, cleans with distilled water again, after drying in air, can obtain zinc oxide nano rod on the zinc metal sheet surface.
The present invention adopts the hydrothermal method of low-cost low-temperature, prepares high quality, high orientation is unified, mean diameter is very little and diameter Distribution is very narrow Zn0 nanometer stick array.Compared with the prior art this array has good ultraviolet photoluminescence, has advantages such as simple to operate, good reproducibility, preparation condition gentleness, product pattern be even.
