用二茂铁催化生长竹节状碳纳米管

Catalytic synthesis of bamboo-shaped carbon nanotubes by ferrocene

利用二茂铁(ferrocene)作催化剂,高温分解乙烯得到具有竹节状的碳纳米管.管内具有明显的圆锥结构,圆锥的排列与管的轴线一致,但形状大小不一.管的直径大约有100nm,并且在其末端并没有观察到催化剂颗粒,少数竹节状碳纳米管还有分叉现象.

The paper reports the catalytic synthesis of bamboo-shaped carbon nanotubes through decomposing ethylene in the presence of the catalytic ferrocene. Inside of the nanotubes, there were many obvious conical structure, which grew along the axis of the nanotube and were different in size. The diamenter of the nanotubes was about (100 nm,) and catalytic particles weren't observed at the tip. Few of bamboo-shaped carbon nanotubes divaricated.
