“…These properties endow wide applications consisting of catalysis, gas storage, sensors and drug delivery [53,54]. Remarkably, MOFs are able to insert a lot of functional groups into the structures via a direct one-step synthesis [55,56]. Whereas, under solvothermal conditions, chemical or thermal instability occur among a number of modified ligands under solvothermal conditions and the desired chemical functionality will not be accomplished.…”

Epoxides are important industrial intermediates applied in a variety of industrial processes. During the production of epoxides, catalysts have played an irreplaceable and unique role. In this review, the historic progress of molybdenum-based catalysts in alkene epoxidation are covered and an outlook on future challenge discussed. Efficient catalysts are demonstrated including soluble molybdenum complexes, polyoxometalates catalysts, molybdenum-containing metal organic frameworks, silica supported molybdenum-based catalysts, polymer supported molybdenum-based catalysts, magnetic molybdenum-based catalysts, hierarchical molybdenum-based catalysts, graphene-based molybdenum containing catalysts, photocatalyzed epoxidation catalysts, and some other systems. The effects of different solvents and oxidants are discussed and the mechanisms of epoxidation are summarized. The challenges and perspectives to further enhance the catalytic performances in alkenes epoxidation are presented.

“…[23] Moreover, Song et al performed the catalytic evaluation of encapsulated Cu II -and Zn II -imidazole-salen complexes as heterogeneous catalysts in Zeolite-Y in the oxidation reactions benzyl alcohol. [24] New Cu (II)/Cu (II)-Mg (II) frameworks of pyridine-2,5-dicarboxylate were applied as a heterogeneous catalyst for epoxidation protocols by Saha et al [25] The catalytic epoxidation of olefins was investigated by involving mixed catalysts of copper-triazole complex and polyoxometalate acid heterogeneously. [26] SiO 2 with multiple functional groups was involved for many applicable processes, for example stabilization of enzymes, bio-catalysis [27] and chemical wastes.…”

N‐Salicylidene amino acid Schiff base sodium sulfonate salt, as a tridentate dibasic chelating ligand, was obtained from the common condensation of salicylaldehyde‐5‐sodium sulfonate with tyrosine (HPST). The internal formed ligand coordinated to Cu2+ ion in an aqueous media affording new Cu (II)‐complex (Cu‐PST), which characterized by various physico‐chemicals spectral tools. The mononuclear complex was evaluated as a homogeneous and heterogeneous catalyst in the (ep)oxidation protocols of 1,2‐cyclooctene and benzyl alcohol. Heterogeneously, Cu‐PST was immobilized on Fe3O4‐SiO2, as nanoparticles. The heterogeneous catalyst was characterized by infrared, X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, energy‐dispersive spectroscopy, Brunauer−Emmett−Teller and magnetism. Homogeneously, the temperature, solvent and oxidant influences were examined in the catalytic reactions to realize the best reaction conditions. Cu‐catalyst exhibited better catalytic performance in the (ep)oxidation processes homogeneously than that in the heterogeneous phase at 80°C for 2 hr in acetonitrile. Reusability of the homogeneous catalyst was for a maximum of three times in the (ep)oxidation reaction, whereas the heterogeneous catalyst was active for six times. A mechanistic pathway was proposed for both catalysts, comparatively.

“…Epoxidation of cyclohexene achieves the 100% of conversion in presence of H ribbon-like 1D chains by intermolecular H-bonding between hydrogen in the imidazolium ion and the free carboxylate oxygens of pdc 2− , this 2D supramolecular structure being crucial to ensure the reaction heterogeneity. Likewise, 1-hexene showed almost complete conversion but increasing the chain length of alkene, the double bond becomes sterically hindered limiting the approach to the active site, and the catalytic activity decreases [40] (Table 1).…”

Metal–organic frameworks (MOFs) are a family of porous crystalline materials that serve in some cases as versatile platforms for catalysis. In this review, we overview the recent developments about the use of these species as heterogeneous catalysts in olefin epoxidation and carbon dioxide cycloaddition. We report the most important results obtained in this field relating them to the presence of specific organic linkers, metal nodes or clusters and mixed-metal species. Recent advances obtained with MOF nanocomposites were also described. Finally we compare the results and summarize the major insights in specific Tables, outlining the major challenges for this emerging field. This work could promote new research aimed at producing coordination polymers and MOFs able to catalyse a broader range of CO2 consuming reactions.
