Abstract

Antimony telluride (Sb₂Te₃) nanoparticles for thermoelectric applications were successfully prepared via a water-based chemical reaction under atmospheric conditions. In this process, we tried to prepare the nanostructured compound by employing both a complexing agent (l-tartaric acid) and a reducing agent (NaBH₄) to stabilize the Sb precursor (SbCl₃) in water and to favor the reaction with Te. It was observed that various products of Te, Sb₂O₃, and Sb ₂Te₃ were individually or simultaneously generated depending on the amount of the complexing and reducing agents used. In order to obtain solely a rhombohedral Sb₂Te₃ compound, the aging time of the reaction needed to be adjusted.
