Yurkov, D. Baranov, A. Kozinkin, Yu. Koksharov, T. Nedoseikina, O. Shvachko, S. Moksin, S. Gubin] Cobalt-containing nanoparticles have been prepared via thermal decomposition of cobalt acetate on the surface of poly(tetrafluoroethylene) (PTFE) microgranules forming a fluidized bed over the surface of hot mineral oil. Using transmission electron microscopy, the average size of the cobalt-containing nanoparticles has been determined to be 3.6 nm. The composition and structure of the nanoparticles have been determined by x-ray diffraction, extended x-ray absorption fine structure spectroscopy, and electron paramagnetic resonance, and the magnetic properties of the synthesized nanomaterial have been studied. The results indicate that the nanoparticles have a core-shell structure, with a metallic cobalt core (≃10 vol%) and a shell consisting of three phases: Co3O4 (≃80%) and small amounts of CoO and CoF2 (≃10%). The fluoride phase results from the interaction of the nanoparticles with surface fluorine atoms of the PTFE microgranules. Pleiades Publishing, Inc., 2006 Yurkov G.
