چکیده
Synthesis of clean double-walled carbon nanotubes by a catalytic chemical vapour deposition (CCVD) method is reported; the catalyst is a Mg(1 - x)Co(x)O solid solution containing additions of Mo oxide; this MgO-based catalyst can be easily removed, leading to gram-scale amounts of clean carbon nanotubes, 77% of which are double-walled carbon nanotubes.

Bundles of identical double-walled carbon nanotubes.
In a sample produced by catalytic chemical vapor deposition (CCVD), the structure of the carbon nanotubes (diameter and helicity) which governs their electronic properties, is determined by electron diffraction. We found that most of the smallest bundles are constituted of identical double-walled carbon nanotubes.
متن کاملA PARAMETRIC STUDY ON THE GROWTH OF SINGLE-WALLED CARBON NANOTUBES OVER CO-MO/MGO NANOCATALYST IN A FLUIDIZED BED REACTOR BY CCVD METHOD
Single-walled carbon nanotubes (SWNTs) with high yield and quality were synthesized using chemical vapor deposition (CVD) over Co-Mo/ MgO nanocatalyst in a fluidized bed reactor. Different parameters such as temperature, the ratio of hydrocarbon source to hydrogen, the flow rate of gas, growth time, the size of catalyst particles, heating rate, and the kind of hydrocarbon source were examined t...
متن کاملSynthesis of Single- and Double-Wall Carbon Nanotubes by Gas Flow-Modified Catalyst-Supported Chemical Vapor Deposition
The synthesis of singleand double-wall carbon nanotubes by gas flow-modified, catalyst-supported chemical vapor deposition (CCVD) is reported. We have investigated the gas flow condition dependence on the synthesis of carbon nanotubes (CNTs) by placing blocks in the CCVD reactor. Carbon nanotubes having large diameters are preferentially grown under turbulent flow conditions. This indicates tha...
متن کاملSynthesis and Characterization of Carbon Nanotubes Catalyzed by TiO2 Supported Ni, Co and Ni-Co Nanoparticles via CCVD
Monometallic and bimetallic Ni and Co catalytic nanoparticles supported on Titanium dioxide (rutile phase) substrate were prepared by wet impregnation method. These nanoparicles were used as catalysts for synthesis of multiwalled carbon nanotubes (MWCNTs) from acetylene decomposition at 700°C by the catalytic chemical vapor deposition (CCVD) technique. The nanomaterials (catalyst and CNTs) were...
متن کاملMolecular Dynamics Simulations of Catalytic CVD Process of Single-Walled Carbon Nanotubes from Alcohol and from Fullerene
Investigation of the formation mechanism is crucial in order to develop a large scale, high-purity, and chirality-controlled generation of single-walled carbon nanotubes (SWNTs). Recently, we have developed a high-quality synthesis technique of SWNTs at relatively low-temperature by catalytic chemical vapor deposition (CCVD) technique using alcohol as the carbon source [1]. In addition, we have...
