Growth of carbon nanotubes and nanofibres in porous anodic alumina film
By acetylene pyrolysis at 650 and 5508C, carbon nanotubes were synthesized successfully in porous alumina templates anodized in sulfuric and/or oxalic acid solution. For templates anodized in oxalic acid followed by boiling in distilled water, thermal decomposition of acetylene at 6508C in the pores results in the formation of carbon nanofibres. For templates anodized in sulfuric acid, only car...
متن کاملFabrication of Nanoporous Template of Aluminum Oxide with High Regularity Using Hard Anodization Method
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum ox...

متن کاملGrowth of well-aligned carbon nanotube arrays on silicon substrates using porous alumina film as a nanotemplate
Aligned, open-tipped carbon nanotube arrays of high density and uniformity were synthesized via a flame method on silicon substrates using a nanoporous template of anodized aluminum oxide from which the nanotubes were grown. The diameter and length of the nanotubes are controlled by the geometry of the aluminum oxide template. These results show the feasibility of integration between carbon nan...
متن کاملGeneral method for the synthesis of crystalline organic nanorods using porous alumina templates.
Nanorods composed of a variety of conjugated organic molecules were synthesized using an anodized alumina template and solvent annealing; detailed study of 200 nm thick 2,7-di-t-butylpyrene rods showed they are crystalline, with single domains extending over several microns.
