Synthesis of monodispersed MFe2O4 (M=Fe, Co, Ni) ferrite nanoparticles: effect of reaction temperature on particle size

We have synthesized different classes of monodispersed MFe2O4 (M=Fe, Co, Ni) nanoparticles by decomposition of metal-organic precursors in organic solvent and explored the reaction temperature effect on the nanoparticles average dimension. We obtained particle sizes in the range of 2-6 nm at different reaction temperatures. Moreover, we have tested some of these nanoparticles as patterned catalyst for CVD synthesis of carbon nanotubes on silicon wafer.
