Paper Abstract

The preliminary results on the laser synthesis of carbonaceous nanoparticles, which exhibit some characteristic features of fullerene/iron complexes, are reported. The nanopowders were obtained by the laser pyrolysis of a gas phase mixture containing hydrocarbon and alternatively iron pentacarbonyl vapors or ferrocene aerosols. The vapors of iron pentacarbonyl were carried out in the reactor through the intermediate of a bubblier; in the runs using ferrocene, this one was solved in benzene and brought into the reaction zone as aerosol. The reactant mixture contained also nitrous oxide, as oxidizer, and sulphur hexafluoride as energy transfer agent. The as- synthesized powders were toluene extracted and characterized by different analytical methods, such as High Performance Liquid Chromatography (HPLC), IR transmission spectroscopy and Moessbauer spectroscopy. The identification of fullerene-metal complexes was performed by Moessbauer spectroscopy. The Moessbauer transmission spectrum has evidenced the formation of both fullerene phases with iron inside and outside the cage.
