Abstract
Fe- and Fe3C-filled carbon nanostructures were synthesised by simply catalytically pyrolysing ferrocene and acetonitrile. The novel hybrid structures fabricated were thoroughly characterised by X-ray diffraction, scanning and transmission electron microscopy, electron energy loss spectroscopy, Raman spectroscopy and magnetic measurement. Aligned arrays of Fe- and Fe3C-filled carbon nanotubes (CNTs) and flower-like Fe3C-filled N-doped multi-branched CNTs clusters were revealed. High coercivity of 670 Oe for the flower-like nanostructures was observed, and the possible mechanism for coercivity enhancement was discussed.
