Recently, Schulte et al. [24] have reported high selectivities to
lower olefins in combination with high activity and low methane
production when using iron supported on nitrogen and oxygen
functionalized-carbon nanotubes (N–CNT, O–CNT) under the
Fischer–Tropsch reaction at 340 C, 25 bar and a H2/CO ratio of
1.8. Their results underline the importance of the weakly interactive
nature of the support to achieve a high catalytic activity.
