Abstract :
We report the preparation and characterization of spinel-structured FeCo2O4 nanoparticles for the efficient and selective oxidation of
sulfides. The as-prepared FeCo2O4 nanoparticles were characterized by powder X-ray diffraction (PXRD), energy-dispersive X-ray analysis
(EDX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). According to TEM images, the size of the
FeCo2O4 particles is identified to be 10-20 nm. The obtained FeCo2O4 nanoparticles were used as an efficient catalyst for oxidation of
sulfides. For all sulfide substrates, very good conversions (69-100%) and selectivities (89-99%) depending on the nature of the sulfide
substrates were obtained. The reusability and recoverability of catalyst show that the catalytic system can be reused fourth times without
significant loss of reactivity and stability.
