Summary:An experimental-computational study of the formation of pure iron nanoparticles, carbon nanoparticles (soot), and combined nanoparticles composed of an iron core coated with a carbon shell during the pyrolysis of iron pentacarbonyl-argon, ethylene-argon, and iron pentacarbonyl-ethylene-argon mixtures, respectively, behind reflected shock waves is carried out. The shape and size distribution of these nanoparticles are examined on a Zeiss Ultra plus ultrahigh-resolution field-emission scanning electron microscope. Detailed kinetic simulations of the formation of the three types particles are performed, which predict the concentration, average size, and size distribution of such particles.
