Recently, iron-based nanoparticles have attracted much attention due to their unique magnetic, physical and chemical properties which offer significant advantages over corresponding bulk materials. We focus on the synthesis of iron-based nanoparticles in a powder form by the plasmochemical method. A surface-wave discharge was sustained in low-pressure argon by 2.45 GHz microwaves. Properties of the discharge were analysed by optical emission spectroscopy and digital photography. The nanopowder captured on filters was investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). We used iron pentacarbonyl Fe(CO)5 as a precursor. The powder consisted of nanoparticles containing mainly ferrite alpha-Fe and magnetite Fe3O4. Size of synthesised nanoparticles was 9 - 14 nm. Since the ferrite nanoparticles tend to oxidise rapidly, we are trying to passivate them by slow oxidation or by introducing cobalt precursor in order to prepare non-oxidising FeCo nanoparticles.
