“…The three synthesized MOFs (MIL-53(Cr), CuBTC, and MIL-101(Cr)) and commercial MOF samples were characterized by XRD and FTIR (see Figures S1 and S2, Supporting Information, respectively); in all cases, the structure was similar to previously published structures , [17] .

“…Tandem reactions, which enable two‐step reactions in one pot, [ 18 ] could be a very interesting route to produce HMF, [ 19 ] which is why it is important to find a bi‐functional catalyst for the isomerization reaction and, then, for the dehydration reaction of fructose. The isomerization reaction is catalyzed by Lewis acid‐type centers, and metal–organic frameworks (MOFs) can act as Lewis acids ,[ 17 ] . [ 20 ] Then, the second reaction (dehydration of fructose to HMF) requires Brønsted‐acid catalysts, [ 3 ] and in this case, a polyoxometalate (POM) was selected.…”

“…[3,4] Fructose can be generated on a large scale during the production of corn syrup using enzymatic catalysts , [5], [6] ; [7] however, fructose is not as abundant a product as glucose, the most abundant sugar in lignocellulosic biomass, and it is easy to obtain. To carry out this reaction starting from glucose (Figure 2), isomerization of glucose to fructose must be achieved using basic [6,[8][9][10][11][12] or acid [5,[13][14][15][16][17] catalysts, with a special interest in recent years being the use of Lewis-acid catalysts.

The direct conversion reaction of glucose to 5‐hydroxymethylfurfural (HMF) is studied using metal organic framework (MOF) as Lewis‐acid catalysts and a polyoxometalate (POM), silicotungstic acid, as a Brønsted‐type acid with a mixture of 1% glucose solution in γ‐valerolactone (GVL)‐10% H2O at 140 °C. The study is carried out with two routes: one using MOF and POM tandem catalysts added independently and the other through the synthesis of a composite material denoted POM@MOF. The activity tests show that the profiles of the conversion and yield of HMF achieved in both routes are similar, with the reactions with MIL‐53(Al) and MIL‐101(Cr) catalysts producing the highest yield of HMF (40% after 8 h of reaction). Stability tests are performed on the POM@MOF catalysts based on MIL‐53(Al) and MIL‐101(Cr). MIL‐53(Al) and HSiW@MIL‐101(Cr) can be reused, showing a progressive loss in HMF yield due to the leaching of POM.

This paper presents the results of the use of MFI zeolite as a catalyst modified with tin and iron. Sn‐MFI and Fe‐MFI catalysts were obtained by ion exchange under hydrothermal conditions with and without ammonium exchange. Catalytic materials were characterized with the use of analytical techniques such as X‐ray diffraction (XRD), Brunauer–Emmett–Teller method (BET), diffuse reflectance spectroscopy in the ultraviolet‐visible range (DRS UV–visible), hydrogen temperature programmed reduction (H2‐TPR), or Fourier transform infrared (FTIR) spectroscopy. The one‐pot catalytic conversion of fructose was performed at 220 °C for 1–5 h. Based on the results, the influence of time and material selection on the products obtained can be seen. Lactic acid (LAC) was obtained with a yield of 68.7% (after 2 h) and levulinic acid (LA) with a yield of 70.9% (after 5 h) with the participation of MFI. In turn, formic acid with a yield of 28.5% (after 5 h) was obtained with the participation of Fe‐MFI.

Glucose to fructose transformation is an essential transformation for the success of biorefinery. Herein, the epitaxial-grafting of Nb in UIO-66 significantly improved the fructose yield. Postsynthesis incorporating Nb in the UIO-66 phenomenally improved the glucose conversion from 31.1 % to 71.8 % and fructose selectivity from 38.2 % to 71.2 %. The incorporation of Nb was confirmed from the FTIR, HR-TEM investigation, EDX analysis, and elemental mapping. The XPS analysis distinctly stated the successful incorporation of Nb and generation of ZrÀ OÀ Nb oxo clusters in the UIO-66 framework. The NH 3 -TPD provided distinguishable information about the chemical interaction of Nb with the UIO-66 framework that resulted in the increase of the acid strength after the Nb incorporation in the UIO-66 catalyst. The content of Nb and reaction parameters, especially temperature and duration, control the glucose to fructose isomerization over glucose to mannose epimerization. The structure-activity relationship was established, and a reaction mechanism was proposed. The catalyst was recycled five times with only a lower decrease in the fructose yield (47.3 % to 42.2 %) than several reported MOFs catalysts. The activity of the developed catalyst was higher or similar to the reported catalysts. The successful grafting of Nb demonstrates that by swiftly modifying the acidity of the catalyst, a superior activity can be achieved.
