High-yield Synthesis of Bamboo-like BN Nanotubes using Self-propagation High Temperature Synthesized Porous Precursor
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 ℃.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.
