摘要

以石墨粉和硼粉为原料，采用机械球磨法，在氨气气氛下球磨120h，然后在1200℃氨气条件下热处理6h，成功的制备出竹节状的B-C-N纳米管.利用X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电镜（TEM）、高分辨透射电子显微镜（HRTEM）以及电子能量损失谱（EELS）等手段进行了表征.纳米管的直径在50～180nm之间，长度可达20μm. EELS定量分析计算结果表明，纳米管由硼、碳和氮元素组成

其B∶C∶N原子比为0.49∶1.00∶0.11，并对纳米管的形成机理进行了初步探讨.

Abstract

B-C-N nanotube with bamboo-like structure was synthesized by heating ball milled mixture of boron powder and graphite powder in flowing ammonia gas stream at 1200℃. The synthesized product was characterized by X-ray powder diffraction (XRD)

scanning electron microscopy (SEM)

transmission electron microscopy (TEM)

electron diffraction (ED)

high-resolution transmission electron microscopy (HRTEM)

and electron energy loss spectroscopy (EELS).The diameter of nanotube was in the range of 50—180 nm and the length is about 20μm.The result of EELS suggested that the nanotube was composed of elements of B

C and N

and the calculated B/C/N atomic ratio was 0.49∶1.00∶0.11.The growth mechanism of B-C-N nanotube was also discussed tentatively.
