Preparation, characterization and photocatalytic evaluation of aluminum doped metal ferrites

摘要： Spinel ferrite nano-particles have shown a growing interest in recent years due to their specific magnetic and electrical properties. In this manuscript different types of metal ferrites were prepared and doped with different amounts of Al. Full characterization of the prepared ferrites was performed using X-Ray spectrophotometer (XRD), Electron paramagnetic resonance(EPR), and BET surface area measurements. Photo catalytic activity for degradation of organic dye was examined also for all samples. The results showed that the doping of ferrites with Aluminum make a dramatic change in the photocatalytic behavior. A correlation between the structure and magnetic proprieties with the photocatalytic behavior was evaluated.
