摘要
Abstract
In the process of preparation of carbon nanotubes(CNTs) by chemical vapor deposition(CVD), bamboo-structured CNTs can be catalytically synthesized from nitric gas environment. However, the formation mechanism of the bamboo-structured CNTs has not been well understood. In the work, the state change of the catalyst particle in the process of growing CNTs by CVD is analyzed, and a new mechanism of forming the bamboo-structured CNTs is put forward after the diffusion of carbon atoms in different states of the catalyst particle is analyzed.关键词
