“…Interesting to note, comparable results could be achieved under mild reaction conditions of this study (75 °C/50 bar, entry 1), suggestive of a tunable active catalytic species. Although previous studies suggests that Fe 2 O 3 and Fe carbides in their various forms are the most active phases, performed under syngas pressure, in Fischer‐Tropsch reactions, it is also possible that Fe 3 C and FeOOH might act, as well, as catalytic active sites . On the other hand it is also reported by Chikkali et al .…”

“…Although previous studies suggests that Fe 2 O 3 and Fe carbides in their various forms are the most active phases, performed under syngas pressure, in Fischer-Tropsch reactions, it is also possible that Fe 3 C and FeOOH might act, as well, as catalytic active sites. [63,64] On the other hand it is also reported by Chikkali et al that acidic nature of catalyst or catalyst support can increase the catalytic activity for hydroformylation. [19] Therefore, it can be assumed that all the phases present in the composite collectively contribute to increasing the catalytic efficiency.…”

Multitasking FeOCN Composite as an Economic, Heterogeneous Catalyst for 1‐Octene Hydroformylation and Hydration Reactions

et al. 2020

A highly efficient multitasking FeOCN composite was synthesized in a single step by the fast heating of an Fe(III) salt and urea. The composite was confirmed by various spectroscopic and analytical techniques which include XRD, FTIR, Raman, FESEM, and XPS analysis. The composite was then investigated for various organic transformations and it was found to be excellent for the hydroformylation of 1‐octene in toluene under 50 bar syngas pressure at 95 °C. The composite was also found to be significantly active for the hydration reactions of alkynes and nitriles under acid‐ and base‐free conditions. The hydration reactions were performed in aqueous methanol at 120 °C and an excellent yield of regioselective products was obtained under optimized reaction conditions.

“…Iron carbides are of great potentials for both CO x hydrogenation and HER process in industry, because iron is an earth‐abundant element. Specifically, FeC x was considered as the active phase in the Fe‐based FTS reaction . Varieties of useful products such as liquid fuels, alkenes, alcohols, and aromatics were obtained with high selectivity over modulated iron carbides catalysts .…”

Catalytic transformation of COx (x = 1, 2) with renewable H2 into valuable fuels and chemicals provides practical processes to mitigate the worldwide energy crisis. Fe‐based catalytic materials are widely used for those reactions due to their abundance and low cost. Novel iron carbides are particularly promising catalytic materials among the reported ferrous catalysts. Recently, a series of strategies has been developed for the preparation of iron carbide nanoparticles and their nanocomposites. Control synthesis of FeCx‐based nanomaterials and their catalytic applications in COx hydrogenation and electrochemical hydrogen evolution reaction (HER) are reviewed. The discussion is focused on the unique catalytic activities of iron carbides in COx hydrogenation and HER and the correlation between structure and catalytic performance. Future synthesis and potential catalytic applications of iron carbides are also summarized.

“…A number of strategies of increasing complexity have been used in order to avoid full encapsulation such as creating hierarchical carbon structures [9] or promoting even more the growth of metal particles, in order to catalyse the formation of carbon nanotubes rather than a randomly interconnected porous network [10]. A prominent example of MOF-templated catalyst synthesis was reported by Santos et al, who studied the formation of a Fe/Fe x C y /C catalyst that exhibited higher stability than benchmark Fe catalysts in the conversion of syngas, a mixture of CO and H 2 [11][12][13][14]. The influence of MOF hierarchical porosity and use of Na or S promoters, typically employed for Fe-catalysed Fischer-Tropsch synthesis (FTS), has been reported to profoundly impact their CO hydrogenation performance [15].…”

We report the use of transition metal precursors impregnated into the pores of CPO-27(Co) metal-organic framework (MOF) crystals prior to pyrolysis as a straightforward strategy for tuning the properties of MOF-derived Co-based catalysts. By adding a Nb inorganic salt prior to pyrolysis hierarchical pores are formed in the resulting carbon and the Co accessible surface area is greatly increased leading to a strong enhancement of CO hydrogenation activity.
