SYNTHESIS AND CHARACTERIZATION MESOPOROUS MAGNETITE IN THE PRESENCE OF BUBBLING NITROGEN

In this paper the synthesis of magnetic ferrite nanoparticles using nitrogen bubbling as stabilizer agent is presented. Co-precipitation methods was used to obtained magnetic ferrite nanoparticle. To determine the structure and morphologies of both types of iron ferrite nanoparticles, with and without nitrogen bubbling were used as methods of analysis: X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and -Emmett-Teller (BET). The Brunauer-Emmett-Teller analysis (BET) shows a mesoporous structure of the magnetic nanoparticles with specific surface area of approximately 156m2/g in the case of stabilized magnetite and an increase of about 166 m2/g in the case of nitrogen bubbling magnetite. The average pore size increases from 5.75 nm for magnetite, to 6.79 nm for bubbled nitrogen magnetite.
