Abstract Submitted to the NANOTUBE'02 Workshop:

Iron encapsulated nano carbon tubes (Fe/nano-CTs) have been prepared using iron compounds and carbon precursor as starting materials by vapor phase reaction. Fe/nano-CTs were obtained by one pot reaction. This process does not need cap elimination procedure or subsequent metal encapsulation step. Fe/nano-CTs were analyzed by transmission electron microscopy (TEM), EDX, X-ray diffraction (XRD) and Raman scattering spectroscopy (RS). TEM-EDX measurement shows that metal is encapsulated inside the nano carbon tubes, and the encapsulated metal is iron. XRD and RS measurements show that the Fe/nano-CTs wall is highly-crystallized graphitic structure.
