Plasma-chemical synthesis of zinc oxide nanotubes

Abstract

Abstract This research presents the results of the synthesis of zinc oxide nanotubes in electric arc plasma. The diameters of these nanotubes are about 120-150 nm, and the length is about several micrometers. Individual nanotubes can reach up to 1 mm. As electron microscopic studies have shown, zinc oxide nanotubes are a “matryoshka”: they are strung on a carbon nanotube. Firstly, a broken carbon nanotube with a diameter of about 30 nm is formed, and then a zinc oxide nanotube grows on it. Moreover, there is no contact between these nanotubes.
