We discover a simple scalable (10 g scale for one batch in this study) route of synthesizing Bi 2 Te 3 nanocomposites in aqueous solution with high yield at room temperature without involving any organic chemicals, capping agents, and surfactants. It is conceivable that the formation mechanism involves interaction between elemental Bi and Te, which takes place at a very slow rate and takes about 2 weeks to form Bi 2 Te 3 . Heat treatment of Bi 2 Te 3 nanocomposite yields a single phase of Bi 2 Te 3 with the relatively high power factor of 24.2 μW/cm∙K 2 at 425 K compared to other solution methods.
