Formation of single-walled carbon nanotubes via reduced-pressure thermal chemical vapor deposition
Article Abstract:
The growth of carbon nanotubes (CNTs) is reported via reduced-pressure thermal chemical vapor deposition (CVD), using a gas mixture of methane/hydrogen and iron/molybdenum catalyst supported by alumina nanoparticles. The investigation of various growth parameters indicate that CNT growth is limited by the gas supply when CVD is performed in the temperature range of 750-900 degree Celsius, whereas the limiting factor for growth at 700 degree Celsius is the rate of carbon diffusion through the catalyst particles.

Low temperature single-wall carbon nanotube synthesis by thermal chemcal vapor deposition
Article Abstract:
The reduced-temperature single-wall carbon nanotubes (SWNTs) were synthesized by the thermal chemical vapor deposition (CVD) of low-pressure ethylene over iron particles supported on silicon wafers. The structures and qualities of SWNTs are extensively studied, due to their outstanding mechanical, electronic, and chemical properties, by atomic force microscopy (SAFM) and micro-Raman spectroscopy.

Long and oriented single-walled carbon nanotubes grown by ethanol chemical vapor deposition
Article Abstract:
The controlled chemical vapor deposition (CVD) growth of single-walled carbon nanotubes (SWNTs), using ethanol as the carbon feedstock and bimetallic CoMo-doped mesoporous silica (SBA 16) as the catalyst is reported. Individual, long and well-oriented SWNTs with relatively narrow size distribution can be grown directly on substrates or across slits by a CVD process.
