| Abstract
| - High-quality double-walled carbon nanotubes (DWNTs) have been produced by catalyticdecomposition of benzene over Fe−Mo/Al2O3 catalyst at 900 °C. The produced carbonmaterials are DWNT bundles free of amorphous carbon covering on the surface. DWNTshave inner tube diameters in the range of 0.69−2.53 nm and outer tube diameters in therange of 1.44−3.30 nm. The interlayer spacing between graphene layers ranges from 0.35to 0.38 nm. Transmission electron microscopy and Raman analysis show that produced carbonmaterials have a low defect level in the atomic carbon structure, indicating the synthesis ofhigh-quality DWNTs. Our results demonstrate that benzene is an ideal carbon feedstock tosynthesize high-purity DWNTs over Fe−Mo/Al2O3 catalyst.

The inner tube diameter of DWNTs is in the range of 0.69−2.53 nm and the outer tube diameter are in the range of 1.44−3.30 nm. The average interlayer spacing is 0.37 nm. High-resolution transmission electron microscopy and Raman spectroscopy indicate that synthesized DWNTs have high quality.
