Abstract

Magnetic iron nanoparticles immersed in a carbon matrix were produced by a combined process of controlled dispersion of Fe3 +  ions in sucrose, thermal decomposition with simultaneous reduction of iron cores and the formation of the porous carbonaceous matrix. The materials were prepared with iron contents of 1, 4 and 8 in %wt in sucrose and heated at 400, 600 and 800°. The samples were analyzed by XRD, Mössbauer spectroscopy, magnetization measurements, TG, SEM and TEM. The materials prepared at 400° are composed essentially of Fe3O4 particles and carbon, while treatments at higher temperatures, e.g. 600 and 800° produced as main phases Fe0 and Fe3C. The Mössbauer spectra of samples heated at 400° showed two sextets characteristic of a magnetite phase and other contributions compatible with Fe3 +  and Fe2 +  phases in a carbonaceous matrix. Samples treated at temperatures above 600° showed the presence of metallic iron with concentrations between 16–43%. The samples heated at 800° produced higher amounts of Fe3C (between 20% and 58%). SEM showed for the iron 8% sample treated at 600–800°C particle sizes smaller than 50 nm. Due to the presence of Fe0 particles in the carbonaceous porous matrix the materials have great potential for application as magnetic adsorbents.
