Large-scale synthesis of aligned carbon nanotubes was achieved by using a method based on chemical vapor deposition catalyzed by iron nanoparticles embedded in mesoporous silica. Scanning electron microscope images show that the nanotubes are approximately perpendicular to the surface of the silica and form an aligned array of isolated tubes with spacings between the tubes of about 100 nanometers. The tubes are up to about 50 micrometers long and well graphitized. The growth direction of the nanotubes may be controlled by the pores from which the nanotubes grow.
通过使用一种基于嵌入介孔二氧化硅中的铁纳米颗粒催化化学气相沉积的方法,实现了对齐碳纳米管的大规模合成。扫描电子显微镜图像显示,纳米管大致垂直于二氧化硅表面,并形成了一个孤立管的对齐阵列,管之间的间距约为100纳米。这些管长达约50微米,且石墨化良好。纳米管的生长方向可以由纳米管生长的孔来控制。
