Role of growth temperature in CVD synthesis of Carbon nanotubes from Ni-Co bimetallic catalysts
The effect of temperature variation on the growth of Carbon Nanotubes (CNTs) using Thermal Chemical Vapor Deposition (TCVD) is presented. Nickel and Cobalt (Ni-Co) thin films on Silicon (Si) substrates were used as catalysts in TCVD technique. Acetylene gas was used in CNTs growth process at the controlled temperature ranges from 850-1000 ̊ C. Catalysts and CNTs characterization was carried out ...

متن کاملControlled Cvd Synthesis of Single-walled Carbon Nanotubes from Alcohol
By using alcohol as carbon source, high-purity single-walled carbon nanotubes (SWNTs) can be generated at relatively low CVD temperatures from metal catalysts supported with zeolite [1]. Based on these findings, we have proposed alcohol catalytic CVD (ACCVD) technique. In addition to the conventional metal particles supported on zeolite, we have developed a simple dip-coat method to directly di...
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/...
