Abstract

original image

A catalytic reaction inside a single-walled carbon nanotube is demonstrated by using encapsulated ferrocene molecules as precursors. A combined spectroscopic and microscopic study unravels the mechanism of catalytic inner tube growth. This confined process provides for the controlled iron growing of double-walled carbon nanotubes and represents a new route for materials design.
