    Abstract

    The graphite encapsulated iron nanoparticles were fabricated by using arc dischargemethod. The synthesized nanoparticles were pre-treated by an inductively-coupled RF Ar plasma and then post-treated by NH3 plasma under various gas pressures and treatment times. Analyses of XPS spectra have been carried out to study the effect of the plasma treatment on the surface modification of nitrogen-containing groups. The morphological changes of the particles surface by plasma treatment have also been analyzed by using HR-TEM. Present results show that the highest values of N/C atomic ratio of 5.4 % is obtained by applying 10 min of Ar plasma pre-treatment and 2 min of NH3 plasma post-treatment conducted in RF power of 80W and gas pressure of 50 Pa.
