Abstract

Nanostructured thermoelectric bismuth telluride (Bi₂Te ₃) powders with various morphologies, such as nanoplates, nanorods, and nanotubes, were prepared by a hydrothermal method based on the reaction between BiCl₃, Te, and sodium ethylenediaminetetraacetate (Na ₂-EDTA) at 150, 180, and 210 °C. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and selected area electron diffraction (SAED). The effect of reaction temperature on the morphology of the Bi₂Te₃ particles was investigated, and the possible mechanism of morphology control was proposed.
