Abstract

A new metal-free catalyst CaSiO₃ was developed to grow carbon nanotubes (CNTs) on a pyrolytic graphite paper tape by an ethanol catalytic chemical vapor deposition method at 1200-1400 °C. The prepared CNTs with a droplet tip had a multi-walled structure and were filled with amorphous CaSiO₃. Temperature, determining the melting of CaSiO₃, was critical for the growth of the CNTs. This new catalyst is suggested to follow the similar roles of transition metals in the growth of CNTs by a molten state to absorb carbon and form CNTs after reaching saturation.
