Resumen

CAO, Yong; LIU, Bingtao; JIAO, Qingze  y  ZHAO, Yun. Preparation of CNx/carbon nanotube intramolecular junctions by switching gas sources in continuous chemical vapour deposition. S.Afr.j.chem. (Online) [online]. 2011, vol.64, pp.67-70. ISSN 1996-840X.

Nitrogen-doped carbon nanotubes (CNx)/carbon nanotube intramolecular junctions were prepared by a simple continuous chemical vapour deposition (CVD) method at 650 °C. The catalyst was obtained by calcination of a layered double hydroxide precursor containing Fe and Mg. By switching between hexane and ethylenediamine repeatedly in the CVD process, multiple intramolecular junctions composed of CNx with a bamboo-like structure and empty hollow carbon nanotubes were observed, and such different structures at both sides of the junctions indicated some interesting properties and offered potential applications for future nanodevices.

Palabras clave : Nitrogen-doped carbon nanotubes; junction; chemical vapour deposition.
