Selective Synthesis of Boron Nitride Nanotubes

摘要：

　　Four types of boron nitride (BN) nanotubes are selectively synthesized by annealing porous precursor in flowing NH3 and NH3/H2 atmosphere at temperature ranging from 1000 to 1200 ℃ in a vertical furnace.The as-synthesized BN nanotubes,including cylinder,wave,bamboo and bubble-chain,are characterized by scanning and transmission electron microscopy.Selectivity of BN nanotubes is estimated as approximately 80 to 95%.The porous precursor B31Fe17(MgO)27 prepared by self-propagation high-temperature synthesis (SHS) method plays a key role in controllable synthesis of the as-grown BN nanotubes.The chemical reaction and annealing mechanism are also discussed.
