A simple template-free solvothermal approach has been developed for the fabrication of Sb2Te3thermoelectric materials. Single-crystalline Sb2Te3nanosheets are 200–300nm in edge lengths and only 18–20nm thick. The nanosheets with no residual organics were hot pressing sintered (HPS) to a p-type nanostructured bulk material, and it still consisted of Sb2Te3nanosheets after HPS and thermoelectric (TE) properties measurements. Relatively good TE properties have been achieved in the Sb2Te3nanosheet sintered bulk sample from 320K to 565K: high electrical conductivity σ (1.69–2.30)×104Ω−1m−1, high Seebeck coefficient S (173–199μVK−1) and low thermal conductivity κ (0.66–0.82Wm−1K−1). Consequently, the dimensionless thermoelectric figure of merit (ZT) of 0.57 at 565K was achieved. Meanwhile, the maximum in ZT was shifted significantly to higher temperature.
