Journal ArticleDOI
Large-scale synthesis of single-wall carbon nanotubes by catalytic chemical vapor deposition (CCVD) method
Jean-François Colomer,C Stephan,S Lefrant,G. Van Tendeloo,Isabelle Willems,Zoltán Kónya,António M. Fonseca,Ch. Laurent,Janos B. Nagy +8 more
TL;DR: In this paper, a large-scale production of single-wall carbon nanotubes (SWNTs) is reported, where large quantities of SWNTs can be synthesized by catalytic decomposition of methane over well-dispersed metal particles supported on MgO at 1000°C.
Journal ArticleDOI
Control of the outer diameter of thin carbon nanotubes synthesized by catalytic decomposition of hydrocarbons
I. Willems,Zoltán Kónya,Jean-François Colomer,G. Van Tendeloo,N. Nagaraju,Antonio Fonseca,Janos B. Nagy +6 more
TL;DR: In this paper, the outer diameter distribution of the carbon nanotubes was characterized by both low and high resolution TEM and it was shown that the inner diameter can be controlled by choosing the appropriate catalyst.
Journal ArticleDOI
Ball milling effect on the structure of single-wall carbon nanotubes
Nathalie Pierard,Antonio Fonseca,Jean-François Colomer,Christophe Bossuot,Jean-Michel Benoit,G. Van Tendeloo,Jean-Paul Pirard,Janos B. Nagy +7 more
TL;DR: In this article, the vibratory mill is used to decrease the single-wall carbon nanotubes (SWNTs) length and to increase their specific surface area, which results in a complete disruption of the tubular structure leading to multi-layered polyaromatic carbon materials observed after 50 h.
Journal ArticleDOI
Synthesis of single- and multi-wall carbon nanotubes over supported catalysts
Antonio Fonseca,Klara Hernadi,P. Piedigrosso,Jean-François Colomer,K. Mukhopadhyay,Roger Doome,S. Lazarescu,László P. Biró,Ph. Lambin,Paul Thiry,D. Bernaerts,Janos B. Nagy +11 more
TL;DR: In this article, the inner and outer diameters of the nanotubes were also measured and the diameter distribution histograms were established by means of transmission electron microscopy and scanning tunneling microscopy.
Journal ArticleDOI
Synthesis of single-wall carbon nanotubes by catalytic decomposition of hydrocarbons
Jean-François Colomer,G. Bister,Isabelle Willems,Zoltán Kónya,António M. Fonseca,Janos B. Nagy,G. Van Tendeloo +6 more
TL;DR: In this paper, single-wall carbon nanotubes (SWNTs) and bundles can be obtained over different types of supported metal catalysts by decomposition of ethylene.
