Abstract

Graphite-like nanostructures including nanotubes and encapsulated polyhedral particles have been obtained by arcing hexagonal boron nitride (h-BN) and tantalum in a nitrogen atmosphere. High resolution electron microscopy (HRTEM), electron energy loss spectroscopy (EELS) and X-ray diffraction studies have been used to study these new materials, which contain B:N ratios of ≈ 1:1. The observations reveal interesting new information on the dynamics of metal cluster catalysed nanostructure formation. The structures provide strong circumstantial evidence for the presence of B₂N₂ squares at the tips, in addition to B₃N₃ hexagons in the main body of the tubes.
