Multiwall Carbon Nanotubes by Hydrothermal Treatment
Keyword(s):
AbstractMultiwall carbon nanotubes have been obtained from carbon soot after hydrothermal treatment at 800°C and 100 MPa. High-resolution electron microscopy (HRTEM) study reveals multiwall carbon nanotubes and carbon nanoparticles made of a hollow core enclosed in well-ordered concentric graphitic layers after hydrothermal treatment. Condensed solid products are free of the amorphous phase. Micro-Raman spectroscopy reveals that the hydrothermal multiwall nanotubes have a characteristic perfectly closed graphitic lattice in the basal plane, without edges or plane terminations.
