Electrochemical and Optical Properties of Tellurium Dioxide (TeO2) Nanoparticles

Abstract

Herein, a facile hydrothermal method was used for the preparation of nanostructured TeO2. Different techniques (X-ray diffraction, transmission electron microscope, and scanning electron microscope) were used for morphology, size, and crystalline structure identification of synthesized TeO2 nanoparticles. Fourier transform infrared and ultraviolet-visible spectroscopies were used for optical properties characterization of nanoparticles. Nanostructured TeO2 having a spherical and uniform shape and particle size ~12 nm that approved via transmission electron microscope. TeO2/ITO glass electrode was fabricated in order to study the electrochemical properties by using cyclic voltammetry and electrochemical impedance spectroscopy. Electrochemical measurements of the fabricated TeO2/indium tin oxide electrode showed that the electrode having excellent sensitivity. Thus, the TeO2nanoparticles can further used for biosensors applications.
