Abstract: The invention provides a preparation method for a vertical single wall carbon nanotube array. The method comprises the following steps: (1) depositing an aluminum film with a thickness of 3 to 20 nanometers on the surface of a substrate; (2) oxidizing the aluminum film at room temperature or at a temperature lower than 200 DEG C as needed; (3) depositing a catalyst layer with a thickness of 0.2 to 1.0 nanometer on the aluminum film or on the oxidized aluminum film; (4) depositing an aluminum film with a thickness of no more than 0.5 nanometer on the catalyst layer; (5) preheating or pretreating a product obtained in step (4) in the presence of 0.1 to 100 millibar low pressure reducing atmosphere; (6) introducing carbon source gas with a concentration of 0.1% to 50% at a growth temperature of 550 to 850 DEG C for growth of the single walled vertical carbon nanotube array. According to the invention, the disadvantages of preparation of single walled carbon nanotubes in the prior art are overcome or at least alleviated; preparation of the single walled vertical carbon nanotube array is realized by using as-simple-as-possible technology and process, and very effective control of the diameter, density and length of the single walled vertical carbon nanotube array can be achieved. | |
