Mount Etna provided the lava rocks used for the direct synthesis of carbon nanotubes and nanofibers by chemical vapor deposition (see image; scale bar: 15 μm). Since the iron oxide particles abundantly present serve as a natural catalyst, this could be an effective approach for the efficient production of nanocarbons.
