Investigation about synthesis of carbon nanotubes with various structures governed by temperature and relevant growth mechanism

摘要：

　　Multi-walled carbon nanotubes (CNTs)/A1 in-situ composite powders over A1 as catalyst carrier had been synthesized successfully using transition metal Ni by chemical vapor deposition.CNTs were mainly characterized by transmission electron microscopy.It was found that reaction temperature had great influences on the structures of carbon products obtained.Detailed discussions according to the structures of CNTs at different reaction temperatures were given.A deduced model for explaining the growth mechanism of CNTs governed by temperature was developed.
