In order to improve the yield of BN nanotubes prepared by ball milling annealing method, a small amount of magnesium was used as catalyst to synthesized boron nitride nanotubes. The results showed that boron nitride nanotubes with high yield, high purity and uniform size were synthesized. The morphology of the synthesized BNNTs is bamboo-like and cylinder-shaped. The diameter of them is about 50 to 150 nm and most of them are 100nm. The length of them is dozens of microns. The existence of end particles indicates that the growth mechanism of BNNTs can be attributed to a gas-liquid-solid growth model. The magnesium catalyzed preparation of boron nitride nanotubes has stable process, high yield and high purity, which is expected to be a good method for large-scale preparation of boron nitride nanotubes.

High Temperature Synthesis

High-yield and high-purity bamboo-like boron nitride nanotubes were synthesized via an effective chemical vapor deposition method by annealing porous precursor under ammonia atmosphere at 1150 °C. The porous precursor, prepared by self-propagation high temperature synthesis method, was the key to bulk synthesis process. The as-synthesized boron nitride nanotubes were characterized by SEM, TEM, HRTEM, XRD, Raman and FTIR spectroscopy. These nanotubes had a bamboo-like structure with uniform diameters about 90 nm and length of more than 10 μm. The associated growth model is proposed in this paper.

We demonstrated that sonication treatment of boron nitride nanotubes (BNNTs) in primary alcohols had led to chemical peeling of their sidewalls through alcoholysis, followed by production of boron nitride nanoribbons (BNNRs).

Bn Nanotubes

A high quantity and yield (up to 85%) of boron nitride (BN) nanotubes have been produced using a mechanothermal method. Elemental boron powders were first mechanically milled at room temperature in NH3 atmosphere and subsequently heated in N2 gas at 1200 °C for up to 16 h. The BN nanotubes obtained have either multiwalled cylindrical or bamboolike structures, suggesting different growth processes. The high formation yield of BN nanotubes is due to a high density of nanostructured nuclei created by an extensive milling treatment.

Colemanite (Ca2B6O11·5H2O) is a natural and new precursor material for the synthesis of boron nitride nanotubes (BNNTs). BNNTs have been synthesized from unprocessed colemanite for the first time. The reaction parameters such as time, catalyst type, catalyst amount and temperature were optimized. It was found that the BNNT formation follows the base growth mechanism, which was initiated with a complex of boron nitride (BN) and iron atoms. The obtained BNNTs were characterized by using SEM, TEM, and spectroscopic techniques such as UV–vis, Raman, FTIR and XRD. The BNNTs were randomly oriented and multi-walled with an outer diameter of 10–30 nm and a wall thickness of 5 nm. This novel BNNT synthesis method can be used to obtain high yield, low cost and pure BNNTs.
