Insight into the role of Fe5C2 in CO2 catalytic hydrogenation to hydrocarbons

Junhui Liu et al.

Summary: This study investigated the relationship between the Fe phase, catalytic performance, and reaction pathways by preparing and using Fe5C2 and K-modified Fe5C2. Results showed that Fe5C2 exhibited high selectivities for CH4 and CO during CO2 conversion, while the addition of K increased selectivity for C-2-C-4 hydrocarbons and C5+ hydrocarbons. This work provides insights into the direct CO2 hydrogenation over Fe5C2 and Fe3O4-Fe5C2 catalysts, advancing the understanding of active phases and reaction pathways of CO2 hydrogenation over iron-based catalysts.

Influence of hydrogen and carbon monoxide on reduction behavior of iron oxide at high temperature: Effect on reduction gas concentrations

Maratun Najiha Abu Tahari et al.

Summary: This study investigated the reduction behavior of hematite at high temperatures using different gas concentrations, revealing that CO is a more efficient reductant than H2 as it can initiate reduction at lower temperatures. However, H2 is faster in completing the reduction process at higher temperatures due to its stronger reducing ability.

Highly dispersed metal doping to ZnZr oxide catalyst for CO2 hydrogenation to methanol: Insight into hydrogen spillover

Di Xu et al.

Summary: The addition of a small amount of Cu into ZnZrOx can enhance the efficiency of CO2 hydrogenation to methanol, with the optimized catalyst showing higher CO2 conversion and methanol yield at comparable methanol selectivity. This improvement is attributed to the enhanced hydrogenation capacity and accelerated transformation of key intermediates caused by hydrogen spillover from well dispersed Cu.

Revealing the activity of different iron carbides for Fischer-Tropsch synthesis

Fangxu Lu et al.

Summary: Research on iron-based catalysts doped with SiO2 or Al2O3 has shown that adjusting the formation of iron carbides can enhance the activity of Fischer-Tropsch synthesis reactions. Characterization results using techniques such as XPS and CO-DRIFTS revealed that SiO2 or Al2O3 affects the electronic state of iron atoms and promotes the formation of Fe-Si or Fe-Al interactions on the surface of iron powder, which in turn plays a key role in the formation of the active phase ε-Fe2C. The content of ε-Fe2C is found to be more beneficial to activity compared to the traditionally recognized active phase χ-Fe5C2 in Fischer-Tropsch synthesis reactions.

The role of H2 in Fe carburization by CO in Fischer-Tropsch catalysts

Jiachun Chai et al.

Summary: The formation of Fe-carbide phases is crucial for Fischer-Tropsch synthesis catalysts. Carburization of Raney Fe showed that CO dissociation occurs at -150 degrees C, while C diffusion into metallic Fe requires higher temperature. The carburization rate increases with H2/CO ratio, leading to predominant formation of carbon-rich ε'-carbide.
