Metal-organic frameworks as catalysts for sugar conversion into platform chemicals: State-of-the-art and prospects

In Situ Spectroscopy of Calcium Fluoride Anchored Metal–Organic Framework Thin Films during Gas Sorption

“…Metal-organic frameworks (MOFs) are known for their high porosity,t unability of components,a nd the resulting versatility in different potential applications.Alarge number of MOF structures have been reported to be active as (opto)-electronic devices,catalysts,and drug-delivery systems. [1][2][3] In addition to those,t he most obvious targeted applications for MOFs is as gas sensors,converters,orfilters due to their high porosity and molecular sieving properties.Aninteresting and essential addition towards these applications is making the MOFs as (thin) films (or membranes), which allows for downgauging the material used and very precise control of the morphological properties. [4][5][6] This can be done by anchoring the MOF nuclei onto as ubstrate,o rs elf-assembled monolayer (SAM) of functional organics,forming surface-mounted MOFs (SURMOFs).…”

Diels–Alder Conversion of Acrylic Acid and 2,5‐Dimethylfuran to para‐Xylene Over Heterogeneous Bi‐BTC Metal‐Organic Framework Catalysts Under Mild Conditions

“…Unlike a simple mixture of metal ions and organic compounds, MOFs exhibit unique properties such as tunable functionalities and various molecular structures, which advance the development of efficient catalysts [21–30] . MOF catalysts typically outperform other heterogeneous catalysts due to their uniform porosity and high density of catalytic active sites [31–33] . Moreover, MOFs can tailor an array of material owing to their composition of organic ligands and metal clusters, which have exhibited excellent catalytic performances in various liquid phase reactions [34] …”

“…[21][22][23][24][25][26][27][28][29][30] MOF catalysts typically outperform other heterogeneous catalysts due to their uniform porosity and high density of catalytic active sites. [31][32][33] Moreover, MOFs can tailor an array of material owing to their composition of organic ligands and metal clusters, which have exhibited excellent catalytic performances in various liquid phase reactions. [34] In this work, we demonstrate a viable and scale-up possible technology for PX production from bio-based sustainable feedstocks, DMF, and AA under mild conditions (160 8C, 10 bar) as a comparison to current industrial practice.…”

Continuous‐Flow Synthesis of 5‐Hydroxymethylfurfural, Furfural from Monosaccharides: A Simple, Fast, and Practical Method

“…[1][2][3][4][5] 2,5-Dimethylfuran has been regarded as a potential platform chemical, which is easily prepared by the hydrodeoxygenation of 5-hydroxymethylfurfural (HMF). [2,[6][7][8] As seen in Figure 1, HMF has been known as an essential raw material in the production of valuable compounds such as levulinic acid, [9][10][11] 2,5-furandicarboxaldehyde and 2,5-furandicarboxylic acid, [12][13] 1,5-bis(5-(hydroxymethyl)furan-2-yl)penta-1,4-dien-3-one [14] , which are known as key precursors for biofuel, polymers, and energy technology. However, high cost is the main obstacle hindering the commercialization of HMF ($1119.30/100 g, 99 % purity, Sigma-Aldrich).…”

“…Thus, the synthesis of HMF from carbohydrates has attracted considerable attention as a crucial step in the manufacturing of biofuels. [1,[15][16][17] Several attempts have been extensively investigated for the preparation of HMF from fructose using Brønsted or Lewis acidic catalysts such as mineral acids, [18] amberlyst-15, [19] phosphate-functionalized porous organic polymers, [20] p-sulfonic acid calix [4]arene, [21] metalorganic frameworks, [6] acidic zeolite, [22][23] metal chlorides, [24] and carbon-based solid acid. [25] Ionic liquids have been known as green reaction media for the dissolution of carbohydrates and conversion of biomass into valuable compounds.…”
