采用生物分子辅助水热法制备了Sb 2 Te 3热电纳米材料。该产品具有由有序排列的板状晶体组成的分级结构。纳米片的直径约为500 nm，厚度约为50 nm。将无有机物残留的Sb 2 Te 3粉末热压烧结（HPS）成p型纳米结构块体材料，并测量其热电（TE）性能。在334 K时，样品具有高的电导率（1.52×104 Ω 1 m-1）、高的塞贝克系数（168 μV K-1）和低的热导率（0.37 W m-1 K-1）。
A simple biomolecule-assisted hydrothermal approach has been developed for the fabrication of Sb2Te3 thermoelectric nanomaterial. The product has a hierarchical structure which is composed of ordered and aligned plate-like crystals. The nanoplates are about 500 nm in diameter and 50 nm of thickness. The Sb2Te3 powders with no residual organics were hot pressing sintered (HPS) to a p-type nanostructured bulk material, and the thermoelectric (TE) properties were measured. High electrical conductivity (1.52×104 Ω1m–1 at 334 K), high Seebeck coefficient S (168 μV K–1 at 544 K) and low thermal conductivity (0.37 W m–1 K–1 at 319 K) were achieved.
