- Abstract
Multiwalled carbon nanotubes (CNTs) have been synthesized by chemical vapor deposition (CVD) from methane and carbon monoxide. The process was catalyzed by cobalt nanoparticles produced via pyrolysis of a solid solution between cobalt and calcium tartrates. The solid solution was characterized by x-ray diffraction, thermogravimetry, and chemical analysis. As shown by transmission electron microscopy, the introduction of water vapor during synthesis increases the CNT content of the resulting material. The field emission current-voltage behavior of the CNTs is shown to depend on CVD conditions.
