Single-Wall Carbon Nanotube Film Grown by Advanced Ethanol Chemical Vapor Deposition Process

An advanced approach has been developed for synthesis of single-wall carbon nanotubes directly on the substrate surface with a low-temperature (700-800 degrees C) catalytic ethanol-chemical vapor deposition without H-2 injection. We use an advanced solution of catalyst CH3-CH2OH/(CH3COO)2Co-4H(2)O(0, 01%)/C3H5(OH)(3) for coating the different substrates with the polished or unpolished surfaces. We have performed the Raman, SEM and TEM investigations of the nanotube films grown. A thickness of the films was very low. The nanotubes with a wide range of diameters (0.8-1.6 nm) constituted the films. An estimated size of the catalytic particles obtained from the advanced solution of catalyst was ranged from 2 to 50 nm. A main range was 2-15 nm.
