Journal ArticleDOI
Water-Assisted Highly Efficient Synthesis of Impurity-Free Single-Walled Carbon Nanotubes
TL;DR: In this article, the authors demonstrate the efficient chemical vapor deposition synthesis of single-walled carbon nanotubes where the activity and lifetime of the catalysts are enhanced by water.
Journal Article
Water-Assisted Highly Efficient Synthesis of Impurity-Free Single-Walled Carbon Nanotubes-``Super-Growth''
TL;DR: Water-stimulated enhanced catalytic activity results in massive growth of superdense and vertically aligned nanotube forests with heights up to 2.5 millimeters that can be easily separated from the catalysts, providing nanotubes material with carbon purity above 99.98%.
Journal ArticleDOI
Size-selective growth of double-walled carbon nanotube forests from engineered iron catalysts.
Takeo Yamada,Tatsunori Namai,Kenji Hata,Don N. Futaba,Kohei Mizuno,Jing Fan,Masako Yudasaka,Masako Yudasaka,Motoo Yumura,Sumio Iijima +9 more
TL;DR: The high efficiency of water-assisted CVD enabled the synthesis of nearly catalyst-free DWNT forests with a carbon purity of 99.95%, which could be templated into organized structures from lithographically patterned catalyst islands.
Journal ArticleDOI
84% catalyst activity of water-assisted growth of single walled carbon nanotube forest characterization by a statistical and macroscopic approach.
Don N. Futaba,Kenji Hata,Tatsunori Namai,Takeo Yamada,Kohei Mizuno,Yuhei Hayamizu,Motoo Yumura,Sumio Iijima +7 more
TL;DR: A statistical and macroscopic analysis to estimate the catalyst activity of water-assisted growth (super-growth) of single-walled nanotubes (SWNT) and to characterize SWNT forests found the SWNT forest to be a very sparse material.
Journal ArticleDOI
Water-Assisted Highly Efficient Synthesis of Single-Walled Carbon Nanotubes Forests from Colloidal Nanoparticle Catalysts
Hidekazu Nishino,Satoshi Yasuda,Tatsunori Namai,Don N. Futaba,Takeo Yamada,Motoo Yumura,Sumio Iijima,Kenji Hata +7 more
TL;DR: In this paper, a single-walled carbon nanotube (SWNT) growth from Fe−Mo nanoparticle catalysts made by colloidal synthesis is demonstrated by water-assisted chemical vapor deposition.
