Abstract :
Iron-doped Al2O3 nanoparticles were prepared via an aqueous combustion synthesis technique using stoichiometric amounts of aluminum nitrate [(Al9NO3)3.9H2O], ferric nitrate [Fe(NO3)3.9H2O], and sucrose (C12H22O11). The heat treatment of the nanoparticles at two temperatures (900 °C and 1100 °C) formed porous agglomerated iron-doped alumina nanoparticles. The heat-treated powders were characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Characterization results showed existence of ?-Al2O3 calcined at 1100 °C. In this study, iron-doped alumina particles with average crystallite size (38.94 nm) were successfully synthesized by using sucrose as dispersion agent and carbon source. Al2O3:Fe nanoparticles can be used in different fields as catalyst support and biocompatible material and for electrical applications.
