✦ Synopsis

Well-aligned carbon nanotubes films were synthesized by a pyrolytic method with aluminum and silicon as substrates.

Ž . The substrate was coated with a thin film of Fe NO . This film was transformed by subsequent heating into Fe O clusters 3 3 2 with a diameter of a few nanometers. Nanotubes were synthesized from acetylene at a temperature between 6308C and 7508C. The nanotubes observed are ''multiwall'' type with a length in the range of 1-10 mm and a diameter of 5-100 nm. Ž . The growth of the nanotubes is a function of the film thickness of deposited Fe NO film as well as the temperature. The 3 3 nanotubes deposited on aluminum exhibit excellent properties as electrode material in electrochemical double layer Ž . capacitors ECDLs .
