The purpose of the present work is to synthesize and characterize of the cobalt oxide compounds nanoparticles by using the solution combustion method. For this purpose, a reactor was designed and fabricated. The features of the reactor are its simplicity and efficiency that allows carrying of combustion reactions in a laboratory small scale. Cobalt(II) nitrate hexahydrate was used as oxidant and glycine as fuel. Synthesis was performed for one hour at 200 °C with the presence of glycine in stoichiometric ratio as the reducing agent. The product was characterized by the X-ray diffraction and field emission scanning electron microscopy analysis. XRD analysis confirmed the successful synthesis of the cobalt compounds nanoparticles. The average size of the crystals formed was calculated to be 50 nm by using the Scherrer equation. FE-SEM analysis revealed the good porous structure of the material. The average size of the particles by this method was estimated to be below 60 nm. Therefore, the importance of the present work is in preparing these nanoparticles by a very cost-effective method.
