Preparation of unique carbon nanotubes and metal-carbon nanotube composites
- Tohoku Univ., Sendai (Japan)
Unique carbon nanotubes were prepared by using anodic aluminium oxide film as template. Carbon was deposited on the pore wall of the alumina by pyrolyzing propylene at 1073K. The template was then dissolved by HF and HCl solution to liberate carbon tubes. The number, length and diameter were exactly same as those of template, and furthermore the thickness of carbon tube could be controlled by the deposition time. Therefore it can be said that we can prepare tailor-made carbon tubes with a very uniform size. This unique tube may have a great potential as catalyst support. An attempt to put some metal component on the inner surface of tube was attempted as follows. The platinum salt in aqueous solution was impregnated in the carbon/template composite, and then it was treated with hydrogen to reduce the salt. Then the template was removed as above. Platinum metal could be loaded only inside of the tube.
