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 ...

Characterization of Single-Walled Carbon Nanotubes (SWNTs) Produced by CO Disproportionation on Co-Mo Catalysts

The disproportionation of CO over Co-Mo/SiO2 catalysts with low Co/Mo ratios results in a high selectivity to single-walled carbon nanotubes (SWNTs) when the reaction is conducted between 700 and 950 °C in a flow of pure CO at a total pressure between 1 and 5 atm. A detailed characterization involving Raman spectroscopy, temperature-programmed oxidation (TPO), and transmission electron microsco...
