报道了一种简便有效的合成定向碳纳米管 (CNTs)的化学气相沉积 (CVD)制备方法。以铁为催化剂 ,乙炔为碳源 ,采用单一反应炉 ,直接在石英基底上沉积催化剂颗粒薄膜 ,成功合成了定向性好、管径均匀的高质量大密度的碳纳米管 A simple and effective chemical vapor deposition (CVD) method for the synthesis of oriented carbon nanotubes (CNTs) was reported. Using iron as a catalyst and acetylene as a carbon source, a single reaction furnace was used to directly deposit a catalyst particle film on a quartz substrate to successfully synthesize high-quality and high-density carbon nanotubes with good directivity and uniform diameter
