“…Decreased selectivity toward undesired light hydrocarbons and increased selectivity toward the target gasoline were achieved using nanosized ZSM‐5 zeolite catalysts. [ 36 ] More recently, hollow ZSM‐5 zeolites were combined with Fe 3 O 4 @MnO 2 catalysts. The resulting materials exhibited high selectivity toward heavy hydrocarbons such as aromatics and gasoline during syngas conversion; the hollow structure reduced over‐cracking and enhanced catalyst stability via suppression of carbon deposition on active sites.…”

However, due to growing concerns regarding crude oil depletion and increasing environmental requirements, finding abundant fossil hydrocarbons with high H 2 /C ratios as well as alternative carbon resources has become crucial to maintaining sustainable, environmentally benign systems that can aid human development. [2] Thus, one-carbon (C1) chemistry, which is the chemistry of C1 molecules that can be derived from sources other than fossil hydrocarbons, including carbon monoxide (CO), carbon dioxide (CO 2), methane (CH 4), methanol (CH 3 OH), and formic acid (HCOOH), has emerged and plays important roles in the energy supply and high-value chemical preparation. [1,3] These C1 resources can be obtained from natural gas, shale gas, coal, biomass, solid wastes, and CO 2 emissions. [3a,4] Extensive studies have been dedicated to the catalytic conversion of C1 molecules, including production of dimethyl ether (DME) and liquid fuels from syngas (a mixture of CO and H 2); production of methanol, light olefins, and even aromatics from CH 4 ; and production of hydrogen from HCOOH. [5] All of these transformations require metallic catalytic species such as single atoms; clusters; or oxides, carbides, or alloy particles (e.g., Rh-, AuPd-, Fe 3 O 4-, and Fe 5 C 2-based catalysts). However, these isolated metallic species suffer from severe sintering due to a lack of confinement effects from supports, which leads to poor catalytic stability and decreased selectivities toward their target products. The efficient production of a specific range of hydrocarbons or oxygenates remains a difficult scientific and technical challenge. Overcoming product selectivity limitations and improving catalyst stabilities via catalyst designs are important areas of research. Zeolites are an important class of shape-selective catalysts with uniform micropores, tunable acidities, and high thermal and hydrothermal stabilities. Over the past decade, they have gained broad popularity and been applied to various industrially important catalytic processes. [6] In particular, the design and development of zeolite-based mono-, bi-, and multifunctional catalysts that combine the advantages of zeolites with those of metallic catalytic species have boosted the application of zeolites to C1 chemistry. As shown in Figure 1, value-added hydrocarbons and oxygenates can be produced from C1 molecules via various catalytic routes over zeolite-based catalysts. By May of 2020, the Structure Commission of the International C1 chemistry, which is the catalytic transformation of C1 molecules including CO, CO 2 , CH 4 , CH 3 OH, and HCOOH, plays an important role in providing energy and chemical supplies while meeting environmental requirements. Zeolites are highly efficient solid catalysts used in the chemical industry. The design and development of zeolite-based mono-, bi-, and multifunctional catalysts has led to a booming application of zeolite-based catalysts to C1 chemistry. Combining the advantages of zeolites and metallic catalytic species has promoted the catal...

“…The enhanced synthesis of C 5 + hydrocarbons demonstrate the ability of novel catalysts to overcome the predictions of the ASF distribution. , The FTS route which is very common has incorporated different strategies to couple mainly Co and Fe-based catalysts with zeolites to orient products toward gasoline. Further research has been undertaken to significantly improve the gasoline quality, since its octane rating is crucial for standardization and engine performance. − Tsubaki’s group can be identified as one popular in the direct syngas conversion to gasoline. ,− Zhang et al rationalized the selectivity for gasoline-ranged isoparaffins via the induction of olefins . Their work compared the influence of bifunctional phase proximity on isoparaffin selectivity.…”

Syngas conversion can play a vital role in providing energy and chemical supplies while meeting environmental requirements as the world gradually shifts toward a net-zero. While prospects of this process cannot be doubted, there is a lingering challenge in distinct product selectivity over the bulk transitional metal catalysts. To advance research in this respect, composite catalysts comprising traditional metal catalysts and zeolites have been deployed to distinct product selectivity while suppressing side reactions. Zeolites are common but highly efficient materials used in the chemical industry for hydroprocessing. Combining the advantages of zeolites and some transition metal catalysts has promoted the catalytic production of various hydrocarbons (e.g., light olefins, aromatics, and liquid fuels) and oxygenates (e.g., methanol, dimethyl ether, formic acid, and higher alcohols) from syngas. In this outlook, a thorough revelation on recent progress in syngas conversion to various products over metal-zeolite composite catalysts is validated. The strategies adopted to couple the metal species and zeolite material into a composite as well as the consequential morphologies for specific product selectivity are highlighted. The key zeolite descriptors that influence catalytic performance, such as framework topologies, proximity and confinement effects, acidities and cations, pore systems, and particle sizes are discussed to provide a deep understanding of the significance of zeolites in syngas conversion. Finally, an outlook regarding challenges and opportunities for syngas conversion using zeolite-based catalysts to meet emerging energy and environmental demands is also presented.

“…However, mild metal-support interaction is preferred to allow sufficient reduction and carbonization of the iron phase [3,6]. Various supports have been used such as silica, alumina, zeolites, and carbon materials such as activated carbon, carbon fiber, graphene, and carbon nanotubes [12][13][14][15]. The carbon materials give the highest activities compared to all known supports [3].…”

Fe-MIL-88B was prepared by a method that utilizes ferric nitrate and terephthalic acid (TPA or H2BDC) as precursors. The catalyst was characterized by TEM, SEM, FTIR, XRD, BET, and TGA. The pyrolyzed MOF (Fe-MIL-88B/C) was then tested for FTS at 300 psi, 300/340°C and H2/CO=1 after reduction under flow of hydrogen at 400°C for 4 hours. GC product results show promising FTS performance and stability compared to previously reported Fe-MOF derived catalysts with CO conversion of 96.90% at 340°C for 40 hours and 97.45% at 300°C for 26 hours.
