Flash microwave synthesis of trevorite nanoparticles

Résumé

Nickel ferrite nanoparticles have several possible applications as cathode materials for rechargeable batteries, named "lithium-ion" batteries. In this study, NiFe2O4 was prepared by microwave induced thermohydrolysis. The obtained nanoparticles were characterized by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), BET method, transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS). All the results show that the microwave one-step flash synthesis leads in a very short time to NiFe2O4 nanoparticles with elementary particles size close to 4-5 nm, and high specific surfaces (close to 240m2/g). Thus, microwave heating appears as an efficient source of energy to produce quickly nanoparticles with complex composition as ferrite.
