Carbon nanotube growth catalyzed by metal nanoparticles formed <i>via</i> the seed effect of metal clusters.

ABSTRACT: Carbon nanotubes (CNTs) are useful nanomaterials owing to their distinct functions that depend on their structure and diameter; therefore, CNTs have recently attracted much attention. Catalytic chemical vapor deposition using metal nanoparticles as catalysts is one of the most useful methods for synthesizing CNTs. However, fine control of the CNT diameter has been technically difficult at the 1 nanometer level owing to the size distribution of metal nanoparticles and the difficulty in suppressing their aggregation during the CNT growth reaction. In this study, we developed a method for simultaneously conducting nanoparticle formation and CNT growth through the in situ preparation of nanoparticles using highly dispersed metal clusters on a support substrate as seeds. In this method,
