Fe Nanoparticle Production by an Atmospheric Cold Plasma Jet

We present a simple method of producing Fe nanoparticles based on the dissociation of ferrocene by a simple single electrode atmospheric cold argon plasma jet. The system is driven by a sinusoidal ac-supply with a peak voltage of 0-30 kV and a frequency of 50 kHz. The average size of iron nanoparticles analyzed by scanning electron microscopy is about 10-30 nm for the gas phase samples, and 30-100 nm for the liquid phase samples. The method should be competitive due to its simplicity and low cost.
