The renaissance of iron-based Fischer-Tropsch synthesis: on the multifaceted catalyst deactivation behaviour.
Emiel de Smit,Bert M. Weckhuysen +1 more
TL;DR: This critical review will summarize the current state of knowledge of the underlying mechanisms for the activation and eventual deactivation of iron-based Fischer-Tropsch catalysts and suggest systematic approaches for relating chemical identity to performance in next generation iron- based catalyst systems.

Fe5C2 nanoparticles: a facile bromide-induced synthesis and as an active phase for Fischer-Tropsch synthesis.
TL;DR: A facile wet-chemical route for the synthesis of Hägg iron carbide nanoparticles, in which bromide was found to be the key inducing agent for the conversion of Fe(CO)(5) to Fe(5)C(2) in the synthetic process, showing enhanced catalytic performance in terms of CO conversion and product selectivity.

Iron oxide surfaces
TL;DR: In this paper, a review of the current status of knowledge regarding the surfaces of the iron oxides, magnetite (Fe3O4), maghemite (γ-Fe2O3), haematite (α-Fe 2O3, and wustite (fe1−xO) is reviewed.

Stability and Reactivity of ϵ−χ−θ Iron Carbide Catalyst Phases in Fischer−Tropsch Synthesis: Controlling μC
Emiel de Smit,Fabrizio Cinquini,Andrew M. Beale,Olga V. Safonova,Wouter van Beek,Philippe Sautet,Bert M. Weckhuysen +6 more
TL;DR: It was shown that a significant part of the Fe phases was present as amorphous carbide phases during high pressure FTS, sometimes in an equivalent amount to the crystalline iron carbide fraction.
