Abstract :
Porous ZnFe2O4 hollow microspheres with a
diameter of about 100–210 nm were successfully prepared
by simple template-free hydrothermal route in ethylene
glycol (EG) solution. The formation mechanism and
properties have been also demonstrated. The structural,
morphological, and magnetic properties of ZnFe2O4 hollow
microspheres were investigated by means of X-ray powder
diffraction (XRD), field emission scanning electron
microscopy, Fourier transform infrared spectroscopy, and
physical properties measurements system. The surface area
was determined using the BET method. XRD and IR
analyses confirm the cubic spinel phase of ZnFe2O4 hollow
microspheres. Every magnetic microsphere is made up of
many ultrafine ZnFe2O4 nanoparticles with porous structure. The as-prepared porous magnetic hollow spheres have
higher surface area and excellent magnetic properties at
room temperature.
