Abstract

Boron oxide vapor was reacted with Fe-filled carbon nanotubes to form FexB-filled nanotubes with composition close to Fe3.5B. The synthesis of the FexB nanowires was performed in the presence of nitrogen at 1400 °C in a graphite crucible. The diameter of the nanowires was approximately that of the starting material due to the confinement of the reaction within the encapsulating nanotubes, and their length was typically in the hundred nanometers range. The inner carbon layer of the filled carbon tubes were converted into boron nitride layers by substitution. The experiment demonstrates the potential use of carbon nanotubes as nanoreactors and high aspect ratio templates.
