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.
