“…These reactors typically consist of a zeolite grown hydrothermally on a thin support, which has gained attention due to its tolerance to chemical and thermal conditions [164–165] . Additionally, the use of organic structure directing agents (OSDA), typically used for zeolite synthesis, allows a uniform seed distribution, resulting in a thin layer without any defects [166] . The application of membrane reactors for CO 2 hydrogenation has been shown to potentially overcome thermodynamic limitations due to the equilibrium, consequently improving the overall conversion and product yield [167–168] .…”

The thermocatalytic conversion of carbon dioxide (CO2) into valuable hydrocarbons presents a promising solution for mitigating anthropogenic CO2 emissions while producing drop‐in replacements for fossil‐derived products. Among the two tandem mechanisms for the direct hydrogenation of CO2, the methanol synthesis coupled with the methanol to hydrocarbon (MTH) reaction offers an improvement over the reverse water‐gas shift coupled with Fischer‐Tropsch synthesis reaction (RWGS‐FTS), as it is not limited Anderson‐Schulz‐Flory distribution and yields higher selectivity towards specific products (e.g., olefins, aromatics, higher hydrocarbons). Herein, we focus on the recent progress achieved through this pathway and outline the existing knowledge gaps. We discuss the challenges involved in the process and highlight the key descriptors in the selection of catalyst components. Finally, we present several potential solutions to circumvent the current challenges, aiming to expedite the advancement of this route toward an efficient CO2 hydrogenation process.

Natural Zeolites are crystalline aluminosilicates with very particular properties, both physical and chemical, such as reversible water adsorption, ion exchange without modifications in their structure, and the adsorption of molecules, acting as a molecular sieve. In the present work, a review of the main applications of Natural Zeolites (ZNs) has been carried out. Essential topics have previously been introduced to understand the nature of ZNs, from their discovery, origin, and main properties; the primary deposits worldwide are also mentioned. The importance of these materials has been increasing over time due to the wide variety of applications implemented, thanks to the creativity and ingenuity of researchers. From ion exchange (II) and adsorption applied to the removal from water of heavy metals, ammonium ion, arsenic, fluorine, etc., to applications in Agriculture (fertilizers, animal nutrition, soil amendment), (the development of agribusiness generates substantial amounts of wastewater). In Medicine (disinfection for Escherichia coli, mycotoxins, bacteria, and antiviral, among others), in Catalysis, Space Project, etc. The above justifies the name that Mumpton gave to the ZNs: “The magic rock.” This review shows some summarized examples and provides other references on each topic. Innovative applications continue to be obtained in the literature, and this “mini-review” is hoped to be helpful.

“…An alternative method, encompassing sol-gel and aerosol-assisted approaches, is proposed due to its enhanced focus on controlling the physical and chemical properties during the synthesis of nanomaterials, particularly resultant zeolites [94,95]. Another challenge in the bottom-up synthesis of zeolites is managing intercrystallite diffusion, which can impede reactant and product movement within the crystalline lattice [96]. To address this, an optimal strategy involves enhancing porosity through methods like dealumination, desilication, and recrystallization.…”

This review focuses on an extensive synopsis of the recent improvements in CO2 hydrogenation over structured zeolites, including their properties, synthesis methods, and characterization. Key features such as bimodal mesoporous structures, surface oxygen vacancies, and the Si/Al ratio are explored for their roles in enhancing catalytic activity. Additionally, the impact of porosity, thermal stability, and structural integrity on the performance of zeolites, as well as their interactions with electrical and plasma environments, are discussed in detail. The synthesis of structured zeolites is analyzed by comparing the advantages and limitations of bottom-up methods, including hard templating, soft templating, and non-templating approaches, to top-down methods, such as dealumination, desilication, and recrystallization. The review addresses the challenges associated with these synthesis techniques, such as pore-induced diffusion limitations, morphological constraints, and maintaining crystal integrity, highlighting the need for innovative solutions and optimization strategies. Advanced characterization techniques are emphasized as essential for understanding the catalytic mechanisms and dynamic behaviors of zeolites, thereby facilitating further research into their efficient and effective use. The study concludes by underscoring the importance of continued research to refine synthesis and characterization methods, which is crucial for optimizing catalytic activity in CO2 hydrogenation. This effort is important for achieving selective catalysis and is paramount to the global initiative to reduce carbon emissions and address climate change.
