Abstract
The synthesis of carbon nanotubes (CNTs) by
chemical vapor deposition (CVD) of isobutane (i‐C4H10)
over sodium‐exchanged K10‐montmorillonite based iron‐
catalysts is investigated. By studying the influence of
iron‐addition (5–25wt%) on the catalyst performances, at
700 °C, an empirical relationship is derived relating the
mass of CNTs synthesized with the exposed surface of
loaded iron, as resulting from simultaneous change of
number, size and dispersion of Fe‐nanoparticles available
for the growth.
