Abstract :
Monodispersed Fe3O4 nanospheres with hollow interior structures are synthesized without any template. Inexpensive and nontoxic reagents such as FeCl3-6H2O and ammonium acetate are used in the ethylene glycol (EG) solution. The hollow structure is formed based on the aggregation of many primary particles, followed by Oswald ripening process. Those nanoparticles exhibit a ferromagnetic behavior with a high saturation magnetization of 81.0 emu/g-1.
