Embodiment

[0013] Weigh 1g of selenium powder into the autoclave, add 20 ml of alcohol, 10 ml of hydrazine, 30 ml of ammonia and 60 ml of water into the autoclave, place the autoclave at a temperature of 150°C for 60 hours, and take out the treated solution, place it in an ultrasonic wave for 30 minutes, then centrifuge and dry the solution. The resulting substance see figure 1 , figure 2 ,from figure 1 It can be proved that the obtained product is a nano-selenium tube. Scanning electron microscope appearance of nano-selenium tubes figure 2 .

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 [0001] The present invention relates to the preparation method of nano selenium tube Background technique [0002] As an important member of the semiconductor family, selenium is not only widely used in the manufacture of rectifiers and photovoltaic cells due to its electrical conductivity and outstanding photoelectric properties, but also is the preferred material for the synthesis of other selenides. In recent years, due to the development of nanotechnology, people have found more superior properties on one-dimensional nano-selenium materials than bulk materials. For example, the tunability of the forbidden band width brought about by the nano-size effect, the improvement of photoconductivity by hundreds of times, and many other potential properties. One-dimensional selenium materials include one-dimensional selenium nanotubes and one-dimensional selenium nanowires. At present, one-dimensional selenium nanowires have been prepare...
