CVD synthesis and purification of single-walled carbon nanotubes on aerogel-supported catalyst
Single-walled carbon nanotubes (SWNTs) were synthesized by disproportionation of carbon monoxide on an aerogel-supported Fe/Mo catalyst. A simple acidic treatment followed by an oxidation process produced a high purity (> 99%) of SWNTs. The nanotubes obtained are bundled SWNTs and free of amorphous-carbon coating. Several factors that affect the yield and the quality of the SWNTs were also stud...
متن کاملA scalable CVD method for the synthesis of single-walled carbon nanotubes with high catalyst productivity
Ž . Single-walled carbon nanotubes SWNT are known to possess superior mechanical and electronic properties. However, the lack of methods for large-scale preparation limits fundamental research and application development of this unique Ž . material. Among all methods currently used for SWNT preparation, chemical vapor deposition CVD method represents the Ž best hope for large-scale production. ...
متن کاملLarge Scale CVD Synthesis of Single-Walled Carbon Nanotubes
The synthesis of bulk amounts of high quality single-walled carbon nanotubes (SWNTs) is accomplished by optimizing the chemical compositions and textural properties of the catalyst material used in the chemical vapor deposition (CVD) of methane. A series of catalysts are derived by systematically varying the catalytic metal compounds and support materials. The optimized catalysts consist of Fe/...
متن کاملDiameter Controlled CVD Synthesis of Single-Walled Carbon Nanotubes
In this study, we systematically investigated the influence of catalyst preparation procedures on the mean diameter of single-walled carbon nanotubes (SWNTs) synthesized by the alcohol catalytic chemical vapor deposition (ACCVD) process. It was found that the SWNT diameter is dependent upon both reduction temperature and time, with lower reduction temperature and/or shorter reduction time resul...
