Recent advances in iron-based catalysts for Fischer–Tropsch to olefins reaction

Harnessing the Synergy of Fe and Co with Carbon Nanofibers for Enhanced CO2 Hydrogenation Performance

“…Peaks at 43.6 and 50.8° correspond to the (110) plane of Fe and the (200) plane of Co in their metallic forms, respectively. The strongest peak at 44.2° is assigned to the (510) plane of Fe 5 C 2 because the (200) plane of Co and (110) plane of Fe are significantly weaker than their monometallic counterparts. , This observation re-emphasized the robust Fe-carbon bonding in the Fe-containing samples, which not only resisted thermal sintering but also fostered robust metal–support interactions, thereby elevating the catalytic performance . In contrast, the monometallic Co nanofiber catalyst, lacking such effective Co-carbon interactions, became deactivated post 1050 °C calcination due to sintering (Figures K and B) …”

A review on sustainable iron oxide nanoparticles: syntheses and applications in organic catalysis and environmental remediation

“…236–238 However, creating FTS catalyst for the production of an array of compounds with greater performance and selectivity still remains a formidable task for chemists, the use of iron-based catalyst can potentially offer a viable solution because such inexpensive, earth-abundant materials have displayed good performance and have capacity to produce various hydrocarbon compounds such as diesel, wax, gasoline to C 2 –C 4 olefins or paraffins. 239–243…”

Research Progress on the Effects of Support and Support Modification on the FTO Reaction Performance of Fe-Based Catalysts

“…SiO 2 mainly affects the dispersion of active components, adsorption and desorption of reactants and products, reduction, carbonization, mechanical strength, and textural properties of catalysts. In addition, a strong metal-support interaction (SMSI) can also change the reaction performance of the catalyst by affecting the acidity and alkalinity of the catalyst surface [7].…”

“…Gao et al [7] found that more and more studies have focused on the addition of promoters and the modification of supports in recent years. The introduction of promoters and the optimization of supports will achieve moderate hydrogenation, control C-C coupling, improve the selection of the catalyst target products (C 2 = ~C4 = ), and achieve the stability and durability of the reaction.…”
