以不负载任何活性组分的阳极氧化铝模板为基底,采用化学气相沉积法在700℃下催化裂解乙炔可控制备纳米碳材料,反应气氛分别为氩气和氢气;产物通过扫描电镜和高分辨透射电镜进行表征。结果表明:当反应气氛为氩气时,阳极氧化铝模板表面沉积了棒体较直的碳纳米棒,这些碳纳米棒形貌规整,平铺在阳极氧化铝模板表面;当反应气氛为氢气时,碳纳米棒的生长方向变成了规整地直立状态;所制备的碳纳米棒为实心的,结构为断断续续的石墨片层组成的波纹状结构。
Based on the anodic alumina template without any active component, the prepared nanocarbon material can be controlled by chemical vapor deposition (FCC) at 700 ℃. The reaction atmosphere is argon and hydrogen respectively. The products are characterized by scanning electron microscopy and high resolution TEM characterization. The results show that when the reaction atmosphere is argon, the rod-shaped carbon nanorods are deposited on the surface of the anodized alumina template. The morphology of the carbon nanorods is flattened and laid on the surface of the anodic alumina template. When the reaction atmosphere is hydrogen , The growth direction of the carbon nanorods becomes regular and upright state; the prepared carbon nanorods are solid, and the structure is a corrugated structure composed of intermittent graphite sheets.
