The effect of titanium (Ti) added to the top layer of an aluminum (Al)/iron (Fe)/Al (bottom) sandwich catalytic substrate was studied. The Ti caused a significant lengthening in the single-wall carbon nanotube forest produced by chemical vapor deposi

We have clarified the reason that aluminum (Al) buffer layers prepared by sputtering on catalytic substrates are stable for single-walled carbon nanotube forest synthesis on chemical vapor deposition. We have focused on the difference between thermal

Single-walled carbon nanotube (SWNT) forest synthesis using antenna-type remote plasma chemical vapor deposition (ARPCVD) is presented. A series of synthesis using carbon monoxide gas as carbon feedstock reveals that the remote conditions, in other w

Molecular dynamics simulations were used to study the initial growth of single-walled carbon nanotubes (SWNTs) on a supported iron cluster (Fe 50 ). Statistical analysis shows that the growth direction of SWNTs becomes more perpendicular to the subst

Using catalytic decomposition, a technique for the production of singe-walled carbon nanotubes (SWCNTs) is reported with a production rate up to 6 g h −1 after purification, and scaling capability up to 220 g h −1 . This is achieved by injection

We explore the role of Mo in Fe:Mo nanocatalyst thermodynamics for low-temperature chemical vapor deposition growth of single walled carbon nanotubes (SWCNTs). By using the size-pressure approximation and ab initio modeling, we prove that for both Fe

Various diameters of alumina-supported Fe catalysts are used to grow single-walled carbon nanotubes (SWCNTs) with chemical vapor decomposition. We find that the reduction of the catalyst size requires an increase of the minimum temperature necessary

In the methods reported for continuous synthesis of carbon single-walled nanotubes (SWNTs), the typical production rates are less than 1 g h-1, after purification. Here we report the development of a new technique with higher production rates, up to
