Abstract
In this letter, we report the catalytic synthesis of a large amount of straight carbon nanotubes using a transition-metal cobalt-nickel/zeolite catalyst. High-resolution transmission electron microscopy images show that they are well graphitized. Raman spectrum shows its peak at 1349 cm-1 (D band) is much weaker than that at 1582 cm-1 (G band). We believe that straight carbon nanotubes contain much less defects than curved nanotubes and might have potential applications in the future.
