The influence of catalyst chemical state and morphology on carbon nanotube growth
Article Abstract:
The differences in the growth rate and characteristics of carbon nanotubes (CNTs), grown by chemical vapor deposition (CVD), are related to the differences in the catalyst chemical states. The results indicate the importance of the interaction between the catalyst and the buffer layer, that controls the chemistry and morphology of the catalyst particles and consequently the growth and CNT characteristics.

Growth of carbon nanotubes with alkaline earth carbonate as support
Article Abstract:
The chemical process occurring prior and during the growth allowed and significant improvement of the carbon deposition rate and quality. Evidence for the active role of the support in the growth process, is explained by the decomposition of the carbonate at the growth temperature.

Direct synthesis of high purity single-walled carbon nanotube fibres by arc discharge
Article Abstract:
The long fibers of high purity single-walled carbon nanotubes (SWNTs) are directly synthesized macroscopically by the modified arc discharge method. The purity of the SWNT in fibers are evaluated by scanning electron microscopy, thermogravimetric analysis, and Raman spectroscopy.
