Abstract

Surface modification of β-FeSi₂ by ZnO is verified to be an effective way to prevent oxidation and enhance thermoelectric (TE) properties of β-FeSi₂. A simple approach is developed to fabricate well-covered, high-density and stable ZnO nanoparticles-coated β-FeSi ₂ (ZnOβ-FeSi₂). First, β-FeSi₂ (n-type Fe_0.98Co_0.02Si₂) particles were prepared by mechanical alloying (MA) and pre-treated in sodium oleate solution to increase the polarity of the surface. Then, the pre-treated β-FeSi ₂ particles were successfully coated by ZnO nanoparticles during sol-gel process. Compared with that of uncoated β-FeSi₂, antioxidation and thermoelectric performance of ZnOβ-FeSi₂ materials is improved distinctly.
