采用热丝化学气相沉积法，以碳纳米管为模板，在典型的金刚石生长条件下合成了氧化钨（WO 3）纳米棒。氧化钨纳米棒生长在两种类型的碳纳米管衬底上，一个是分散的多壁碳纳米管的Si [100]晶片，另一个是新生长的多壁碳纳米管薄膜。与平面Si [100]表面相比，模板化生长导致氧化钨覆盖的表面积增加了一个数量级，当与以各种形式如柱和片生长CNT的灵活性结合时[K. Hata，D. N.双叶角Mizuno，T.纳迈湾尤穆拉，S。Iijima，Science 306（2004）1362-1364.]，可以有效地用于场致发射、气体传感和催化应用。(c)2005 Elsevier B. V.保留所有权利。
Synthesis of tungsten oxide (WO3) nanorods using CNTs as templates under typical diamond growing conditions in a hot-filament chemical vapor deposition system is described. Tungsten oxide nanorods were grown on two types of CNT substrates, a Si [100] wafer with dispersed multiwalled CNT and a fresh-grown multiwalled CNT film. The templated growth resulted in an order of magnitude increase in surface area covered by the tungsten oxide compared to a planar Si [100] surface, which when combined with the flexibility of growing CNTs in various forms like pillars and sheets [K. Hata, D. N. Futaba, K. Mizuno, T. Namai, M. Yumura, S. Iijima, Science 306 (2004) 1362-1364.], can be effectively utilized in field emission, gas sensing and catalytic applications.
