催化无基体法制备碳纳米管

Preparation of Carbon Nanotube by the Method of Deep Catalytic Cracking without Matrix

用一种新的催化裂解法 ,制备出了直径在 2 0～ 30nm ,长度为 2 0 0 μm的碳纳米管。在此方法中 ,繁琐的催化剂制备工艺被省略 ,催化剂前驱体在载气带动下直接进入反应器。另外还发现两类结构独特的碳纳米管。

Quality carbon nanotubes were prepared by a new type of deep catalytic cracking method.The diameter of products is 20-30 nm and the length is 200 μm.In this method,catalyst need not be prepared before the reaction,and the catalyst precusor was brought directly into the reactor by the carrier gas.Furthermore,two kinds of unique carbon nanotubes not reported in published documents were discovered with TEM.
