Abstract

A facile energy-saving route is developed for fabricating Sb₂Te₃-Te nanocomposites and nanosized Te powders. The fabrication route not only avoids using organic chemicals, but also keeps the energy consumption to a minimum. The fabrication procedure involves two steps. Energetic precursors of nanosized powders of Sb and Te are produced at room temperature followed by hot pressing at 400°C under 70 MPa for 1 h. The resulting Sb₂Te₃-Te nanocomposite exhibits enhanced power factor. The dimensionless figure of merit zT value of the Sb₂Te₃-Te nanocomposite is 0.29 at 475 K.

Keywords: Sb2Te3; energy-saving synthesis; nanoparticles; thermoelectric composites.
