Preferential growth of single-walled carbon nanotubes on silica spheres by chemical vapor deposition.
The preferential growth of single-walled carbon nanotubes (SWNTs) on silica spheres with various diameters was realized for the first time by chemical vapor deposition (CVD) of methane. SWNTs tend to wrap the silica spheres to form a new superstructure of uniform SWNT nanoclaws when the diameters of the silica spheres are larger than 400 nm. The SWNTs obtained on silica spheres have highly grap...
متن کاملLarge-Scale Synthesis of Rings of Bundled Single-Walled Carbon Nanotubes by Floating Chemical Vapor Deposition
Since their discovery, single-walled carbon nanotubes (SWNTs) have attracted considerable attention due to their unique chemical and physical properties, as well as their promise in the area of materials chemistry. Using previously reported synthetic methods, carbon nanotubes (CNTs) are always grown as long strings, and this string shape largely determines their properties. CNTs with annular ge...
متن کاملChemical vapor deposition synthesis of near-zigzag single-walled carbon nanotubes with stable tube-catalyst interface
Chemical vapor deposition (CVD) growth is regarded as the most promising method for realizing structure-specific single-walled carbon nanotube (SWNT) growth. In the past 20 years, many efforts dedicated to chirality-selective SWNT growth using various strategies have been reported. However, normal CVD growth under constant conditions could not fully optimize the chirality because the randomly f...
متن کاملParametric Study of Single-Walled Carbon Nanotubes Using Alcohol Catalytic Chemical Vapor Deposition
Single-walled carbon nanotubes (SWNTs) were synthesized both in powder form and on substrates using alcohol catalytic chemical vapor deposition method (ACCVD). A detailed parametric study was conducted. As-grown SWNTs were analyzed using transmission electron microscopy (HRTEM), field-emission scanning electron microscopy (FE-SEM) and Raman spectroscopy. Nucleation and growth of SWNTs occurred ...
متن کاملHot wire chemical vapor deposition of isolated carbon single-walled nanotubes
Hot wire chemical vapor deposition ~HWCVD! has been employed for the continuous generation of carbon single-walled nanotube ~SWNT! materials. Interestingly, transmission electron microscopy analyses revealed only the presence of isolated SWNTs, rather than nanotubes existing in bundles. An analysis of the growth mechanism explaining the production of isolated SWNTs is provided. Also, the Raman ...
