Abstract

Multiwall carbon nanotubes (MWNTs) were synthesized via the decomposition of CCl₄ in supercritical CO₂ at 175 °C and 27.6 MPa using an iron-encapsulated dendrimer as a growth catalyst. The average diameter of resultant nanotubes was 20-25 nm, obtained after a 24-h reaction time. Our conditions represent the first application for CX₄ precursors, as well as the lowest-reported temperature regime for carbon nanotube growth, allowing the use of other temperature-sensitive catalytic substrates.
