Abstract

Iron-filled nitrogen-doped carbon (Fe@CN_x) nanotubes were prepared by an in situ chemical vapor deposition with ferrocene as catalyst and ethylenediamine as carbon and nitrogen sources. The as-grown products were characterized using an X-ray diffractometer, transmission electron microscope, X-ray photoelectron spectroscopy, thermogravimetric analyzer and vibrating sample magnetometer. It was found that the "bamboo-like" N-doped carbon nanotubes were filled with 41.1 wt% of Fe nanoparticles. The coercivity and saturation magnetization of Fe@CN_x nanotubes were much larger than those of carbon nanotubes and CN_x nanotubes.
