Doping in carbon nanotubes and graphene makes them interesting materials. Doping brings significant changes in their electronic and other properties which make them suitable for specific applications. This review presents the synthetic procedures, properties and applications of boron- and nitrogen-doped carbon nanotubes and graphene. Multi-walled, single-walled and double-walled carbon nanotubes as well as graphene can be doped with boron and nitrogen. B 2H 6 has been generally used as the boron source while NH 3 or pyridine is employed as the nitrogen source. Doping carbon nanotubes and graphene with boron and nitrogen brings about significant changes in the electronic structure and properties. Such doping not only results in desirable properties but also allows manipulation of properties for specific purposes. Doping with boron- and nitrogen-causes marked changes in the Raman spectra of the carbon nanostructures. In this article, we present the synthesis, characterization and properties of boron- and nitrogen-doped carbon nanotubes and graphene.
