Synthesis of FeSb2 Nanorods and Nanoparticles by Solvothermal Synthesis Routes (Briefing Charts)

摘要

FeSb2 has recently been considered as a novel thermoelectric material due to a Seebeck coefficient of approximately -45000 microVK-1 and a thermoelectric power factor of approximately 2300 microWK-2/cm at low temperatures. However, its thermoelectric potential is limited by a high thermal conductivity. To lower the thermal conductivity, both nanorods and nanoparticles of FeSb2 were synthesized. Nanorods were synthesized following a previously published solvothermal synthesis in ethanol. Nanoparticles were synthesized using a novel sodium naphthalenide reduction in triglyme at ambient pressure. XRD was used to characterize both materials.
