Abstract

The Co₃O₄ nanocomposite was synthesized by an ion-exchange of cobalt ions and Y zeolite in the presence of sodium hydroxide and calcination treatment. The products were characterized by X-ray diffraction (XRD), Raman analysis, scanning electron microscope (SEM), transmission electron microscope (TEM), BET, Energy-dispersive X-ray spectroscopy (EDX) and Fourier transform infrared (FTIR) spectroscopy. The sizes of the migrated Co ₃O₄ particles out of Y zeolite super cage were in the range of 29 ± 5 nm. Finally, the magnetic property of as-obtained product was investigated in a vibrating sample magnetometer (VSM). This nanocomposite showed a paramagnetic behavior at room temperature.
