Abstract :
Hollow CoFe2O4 spheres consisted of CoFe2O4
nanoparticles were synthesized by a facile solvothermal
treatment of an ethylene glycol solution of FeCl3 6H2O,
CoCl2 6H2O, and NaAc at 200 C in the presence of
polyethylene glycol and oleic acid. The products were
characterized by powder X-ray diffraction, transmission
electron microscopy, selected area electron diffraction,
high-resolution transmission microscopy, scanning electron
microscopy. The magnetic properties were evaluated using
a vibrating sample magnetometer. The probable mechanism
of the formation of Hollow CoFe2O4 spheres was
discussed.
