“…The chemical fixation of carbon dioxide (CO 2 ) is one of the major research interests today due to the greenhouse effects on the environment . So, MOFs as materials have been used to remove greenhouse gases by chemically fixing carbon dioxide (CO 2 ) into beneficial compounds that have been investigated by researchers in both pharmaceutical laboratories and academic interests. − To develop this issue, Molla et al synthesized heterogeneous AgNPs/Co-MOF for carbon dioxide capture due to extra-high porosity and tunable nature of pores. This compound was able to complete the carboxylation of terminal alkynes under CO 2 atmosphere due to highly reactive AgNPs …”

Catalysts played a crucial role in advancing modern human civilization, from ancient times to the industrial revolution. Due to high cost and limited availability of traditional catalysts, there is a need to develop cost-effective, high-activity, and nonprecious metal-based electrocatalysts. Metal−organic frameworks (MOFs) have emerged as an ideal candidate for heterogeneous catalysis due to their physicochemical properties, hybrid inorganic/organic structures, uncoordinated metal sites, and accessible organic sections. MOFs are high nanoporous crystalline materials that can be used as catalysts to facilitate polymerization reactions. Their chemical and structural diversity make them effective for various reactions compared to traditional catalysts. MOFs have been applied in gas storage and separation, ion-exchange, drug delivery, luminescence, sensing, nanofilters, water purification, and catalysis. The review focuses on MOF-enabled heterogeneous catalysis for value-added compound production, including alcohol oxidation, olefin oligomerization, and polymerization reactions. MOFs offer tunable porosity, high spatial density, and single-crystal XRD control over catalyst properties. In this review, MOFs were focused on reactions of CO 2 fixation, CO 2 reduction, and photoelectrochemical water splitting. Overall, MOFs have great potential as versatile catalysts for diverse applications in the future.

“…Ionic liquids (ILs) are promising separation agents − owing to their numerous unique properties, such as nonvolatility, wide liquid range, high electrical conductivity, good thermal stability, high heat capacity, wide electrochemical window, local structural order, strong dissolution ability for both organic and inorganic substances, ease of recovery and recycling, etc. − To date, numerous studies have reported the application of ILs in chemical reactions, materials science, extraction and separation, gas absorption and separation, and the development of pharmaceutics and medicines. − Since the first successful extraction and separation of benzene derivatives from aqueous solutions using [BMIM][PF 6 ] by Rogers et al in 1998, the application of ILs in extraction processes has become increasingly widespread, including in the extraction of hydrocarbons, − organic acids, alcohols, , amines, natural products, − and metal ions. − Hydrocarbon extraction using ILs mainly consists of the extraction of monocyclic aromatic hydrocarbons (MAHs) from aliphatics (e.g., separation of benzene/hexane, toluene/octane, benzene/cyclohexane, ethylbenzene/cyclooctane, and hexane/cyclohexane systems), − extractive desulfurization (EDS) , and extractive denitrification (EDN) , from fuel oils, and separation of olefins/alkanes with high carbon numbers. , Recently, ILs have been successfully applied in extracting polycyclic aromatic hydrocarbons (PAHs) from catalytic diesel, which will undoubtedly expand the application scope of ILs to aromatics extraction from fuel oils. , In the past decade, authors have reviewed the application of ILs in extractive separation of aromatics/aliphatics, EDS, ,− and EDN, …”

Separation and reaction processes are key components employed in the modern chemical industry, and the former accounts for the majority of the energy consumption therein. In particular, hydrocarbon separation and purification processes, such as aromatics extraction, desulfurization, and denitrification, are challenging in petroleum refinement, an industrial cornerstone that provides raw materials for products used in human activities. The major technical shortcomings in solvent extraction are volatile solvent loss, product entrainment leading to secondary pollution, low separation efficiency, and high regeneration energy consumption due to the use of traditional organic solvents with high boiling points as extraction agents. Ionic liquids (ILs), a class of designable functional solvents or materials, have been widely used in chemical separation processes to replace conventional organic solvents after nearly 30 years of rapid development. Herein, we provide a systematic and comprehensive review of the state-of-the-art progress in ILs in the field of extractive hydrocarbon separation (i.e., aromatics extraction, desulfurization, and denitrification) including (i) molecular thermodynamic models of IL systems that enable rapid large-scale screening of IL candidates and phase equilibrium prediction of extraction processes; (ii) structure–property relationships between anionic and cationic structures of ILs and their separation performance (i.e., selectivity and distribution coefficients); (iii) IL-related extractive separation mechanisms (e.g., the magnitude, strength, and sites of intermolecular interactions depending on the separation system and IL structure); and (iv) process simulation and design of IL-related extraction at the industrial scale based on validated thermodynamic models. In short, this Review provides an easy-to-read exhaustive reference on IL-related extractive separation of hydrocarbon mixtures from the multiscale perspective of molecules, thermodynamics, and processes. It also extends to progress in IL analogs, deep eutectic solvents (DESs) in this research area, and discusses the current challenges faced by ILs in related separation fields as well as future directions and opportunities.
