Abstract
A process for preparing selenium nanotubes includes reaction between Se powder, water, alcohol, ammonia water and hydrazine at 100-500 deg.c for 1-200 hr, treating the resultant solution by ultrasonic waves for 1-10 hr, centrifugal treating and drying. Its advantage is no environmental pollution.
Description
Technical field
The present invention relates to the preparation method of nano selenium tube
Background technology
Selenium simple substance is as the important a member in the semi-conductor family, not only makes rectifier and photocell because of its electroconductibility and outstanding photoelectric characteristic are widely used in, and is the preferred material of synthetic other selenide.In recent years because the development of nanotechnology makes people find the character more superior than block materials on 1-dimention nano selenium material.Such as the adjustability of the energy gap of being brought by nanometer size effect, the raising of photoconductive property hundreds of times also has other many potential performances.One dimension selenium material comprises one dimension selenium nanotube and one dimension selenium nano wire.One dimension selenium nano wire is made at present, but the one dimension selenium nanotube also is not produced.
Summary of the invention
The purpose of this invention is to provide a kind of method for preparing nano selenium tube.
Preparation process of the present invention is as follows:
1) the simple substance selenium powder is put into autoclave, add entry, alcohol, ammoniacal liquor and hydrazine, water: alcohol: ammoniacal liquor in the autoclave the inside: the volume ratio of hydrazine is 2~10: 1~10: 3~10: 6~10;
2) autoclave is placed under 100~500 ℃ the temperature handled 1~200 hour;
3) take out the solution of above-mentioned processing, it was placed in the ultrasonic wave ultrasonic 1~10 hour, with solution centrifugal, drying, obtain nano selenium tube then.
Preparation method of the present invention is simple, and production cost is low, environmentally safe in the manufacturing processed.
Description of drawings
Fig. 1 is the transmission electron microscope photo of selenium pipe, and the little figure in the upper right corner is the electron diffraction photo of selenium pipe;
Fig. 2 is the stereoscan photograph of selenium pipe.
Embodiment
Further specify the present invention below in conjunction with example.
Embodiment
Claim the 1g selenium powder to put into autoclave, in autoclave, add 20 ml ethanols, 10 milliliters of hydrazines, 30 milliliters of ammoniacal liquor and 60 ml waters, autoclave is placed under 150 ℃ the temperature and handled 60 hours, take out the solution of above-mentioned processing, it was placed in the ultrasonic wave ultrasonic 30 minutes, then solution centrifugal, drying.The gained material is seen Fig. 1, Fig. 2, from the transmission electron microscope photo of Fig. 1, can prove that gains are nano selenium tubes.The scanning electron microscope appearance of nano selenium tube resembles sees Fig. 2.
