用CVD法制备纳米碳管催化剂的工艺研究

Investigating on the Preparing Technology of Catalyst Used in Carbon Nano-Tube Preparation by CVD Method

用CVD法制备纳米碳管的关键是催化剂。在催化剂的制备工艺过程中 ,配料比、沉淀条件、还原、灼烧、干燥的时间和温度等不同、载体的不同 ,都会影响纳米碳管的产量。

The key of preparing carbon nano-tube by CVD is its catalyst In the process of catalyst preparation, there are many factors to affect the production quantity of carbon nano-tube, the factors includes reducing action, depositing condition, drying time, drying temperature, burning lost, carrying material, and so on, so the optimization technology data must be got by testing and investigating
