Abstract:
Sacrificing the catalyst: Controlled reduction of a spinel-type Co–Mn-based mixed oxide leads to a collapse of the oxide structure and the nucleation of 10 nm Co particles. This catalyst facilitates the growth of homogeneous carbon nanotubes with yields 2–9 times higher than those reported to date, indicating that carbon nanotubes might finally become a commodity chemical.
