Different conditions for the preparation of CoSb3 nanomaterials and additives were studied to improve their thermoelectric properties. The experimental results show that hydrothermal method can effectively prepare CoSb3 nanometer powders with high crystallinity and small particle size, and appropriate additives can further improve the thermoelectric properties of nanomaterials. In addition, the effects of factors such as calcination temperature, calcination time, and oxidation-reduction process on the crystallization, particle size, and thermoelectric properties of CoSb3 nanomaterials were also studied during the preparation process. This study has a certain reference value for understanding the preparation and performance optimization of CoSb3-based thermoelectric materials.Keywords: CoSb3, hydrothermal method, nanomaterials, thermoelectric properties
