Abstract	Nanostructured CoSb$_{3}$ was prepared via a polyol method using different Co:Sb molar ratios in the reactant precursors. X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM) were used to characterize the prepared products. Thermoelectric properties of the samples were measured from room temperature to around 500°C. The electrical resistivity and Seebeck coefficient were found to increase with increasing Sb content in the reactant precursors. The sample with a reactant precursor Co:Sb molar ratio of 1:4.75 exhibited the lowest total and lattice thermal conductivity, and the highest ZT value of 0.16 was obtained for this sample at about 450°C.
