The direct substitution of carbon atoms in the hexagonal lattice of carbon nanotubes by heteroatoms has been explored over the last three decades. However, incorporating B specifically has been one of the most challenging tasks. Many experimental problems have been encountered towards the upscalabiliy of the synthesis in processes,
specially in commonly used methods like chemical vapor deposition (CVD). During this research, different solutions were explored. For instance, a high vacuum CVD system was adapted for the evaporation of a unique solid source that contained boron and carbon in its stoichiometry.
CBx-SWNT, control their degree of purity, and to understand the B incorporation profile. This leaves the research status at the level that perspective applications can start to be envisaged
