Synthesis and characterization of high-quality double-walled carbon nanotubes by catalytic decomposition of alcohol.
We report the synthesis of high-quality double-walled carbon nanotubes without defects by catalytic decomposition of alcohol over an Fe-Mo/Al2O3 catalyst; the synthesized DWNTs have outer diameters in the range of 1.52-3.54 nm and an average interlayer distance of 0.38 nm between graphene layers.
متن کاملGram-scale CCVD synthesis of double-walled carbon nanotubes.
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.

متن کاملBundles 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 کاملBuckling of Double-walled Carbon Nanotubes
This paper is concerned with the buckling of double-walled carbon nanotubes (DWCNTs) under axial load. The DWCNTs are modelled as two cylindrical shells, one shell nested in the other and Winkler springs are introduced to connect them in order to simulate the van der Waals forces between the two nanotubes. By using the Donnell thin shell theory, we derive the governing equations for the bucklin...
