Fe Nanoparticle Production by an Atmospheric Cold Plasma Jet

Abstract

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.
