Dendrimer-templated Fe nanoparticles for the growth of single-wall carbon nanotubes by plasma-enhanced CVD

Article Abstract:

Single-walled carbon nanotubes (SNWTs) can be grown microwave plasma-enhanced chemical vapor deposition (PECVD) by using dendrimer-templated and stabilized, nearly monodispersed [Fe.sub.2][O.sub.3] nanoparticles. The results can be used to promote the use of exposed Fe nanoparticles supported on different substrates for the growth of high-quality SWNTs by PECVD.

Synthesis of double-walled carbon nanotubes by catalytic chemical vapor deposition and their field emission properties

Article Abstract:

The synthesis of double-walled carbon nanotubes (DWCNTs) by catalytic chemical vapor deposition (CVD) using Fe-Mo/MgO as a catalyst at 1000 degree C under the mixture of methane and hydrogen gas is described. The field emission properties and morphology of screen-printed DWCNT films containing glass frit are investigated.

Controlling the diameter of carbon nanotubes in chemical vapor deposition method by carbon feeding

Article Abstract:

The effect of carbon feeding rate on the diameter distribution of chemical vapor deposition (CVD)-grown single-walled carbon nanotubes (SWNTs) is studied. It is found that the diameters of SWNTs are closely related to the carbon feeding rate by selective activation of nanoparticles.
