Synthesis and study of properties of Zn nanotubes

Abstract

This paper describes the method of synthesis of Zn-based nanotubes using electrochemical deposition, as well as characterizes their morphological and conductive properties. Track membranes based on polyethylene terephthalate (PET) with a thickness of 12 microns with pore diameters of 380±10 nm were used as templates. Characterization of the structural features was carried out by scanning electron microscopy (SEM), energy dispersive analysis (EDA) and X-ray diffractometric analysis (XRD), and indirectly, during the study of electrical conductivity.
Calculation of the average crystallite sizes showed that the reduction in the intensity of the oxide phase ZnO reduces the size of the crystallites from 41.52 nm at 1.25 V to 29.34 nm at 1.75 V. The number of defects, which interferes with the movement of electrons, reduced with the decreasing of the average size of crystallites in the nanotubes. The number of defects directly affected the conductive properties of Zn based nanotubes.
