Heteroatomic Single-Wall Nanotubes Made of Boron, Carbon, and Nitrogen

In this chapter, we review the current status of research on heteroatomic single-walled nanotubes (SWNTs): boron nitride (BN), B–C, C–N, and B–C–N. We present developments in the synthesis, the characterization, and the properties measurements and theoretical studies. These nanotubes have unique properties when compared with that of their carbon counterparts. For instance, BN-SWNTs are chemically inert, resistant to oxidation at high-temperature, and most importantly, possess a uniform electronic structure that is independent of their geometry. In the first part of this chapter, we review the different synthesis methods employed to produce these nanotubes (high and medium-low temperature processes). We then turn to the study of the atomic structure of these nanomaterials by different transmission electron microscopy techniques as well as we review the works concerning the growth mechanism of these nanotubes. Finally, the main physical (electronic, vibrational, optical, mechanical, electromechanical, and thermal) and chemical (functionalization and hydrogen storage) properties of these heteroatomic SWNTs, particularly the case of BN, are outlined, followed by the presentation of the potential applications of these nanoobjects.
