本文介绍了一种通过脉冲丝放电（PWD）和高温退火合成氮化硼纳米片(BNNS)/氮化硼纳米管(BNNT) -Fe纳米复合材料的简单方法。通过在氮气环境中放电包覆bnns的铁丝，合成了BNNS-Fe纳米复合材料。将合成的纳米复合材料在1200℃下退火，得到bnnt。发现铁纳米颗粒作为生长bnnt的催化剂。
This letter presents a simple method to synthesize boron nitride nanosheet (BNNS)/boron nitride nanotube (BNNT)–Fe nanocomposites via pulsed wire discharge (PWD) and high-temperature annealing. BNNS–Fe nanocomposites were synthesized by discharging BNNS-coated Fe wires in ambient nitrogen. The as-synthesized nanocomposites were annealed at 1200 °C to develop BNNTs. The Fe nanoparticles were found as the catalysts for growing BNNTs.
