“…In Figure 1b, it can be seen that after calcination in the air, diffraction peaks of hydrotalcite is disappearing and instead new eighty diffraction peaks were observed. The presence of new paek at a 2θ value of 19,31,36,39,45,55,59 and 65 confirms the presence of oxide spinel phase (JCPDS 38-0814). Thus, after calcination XRD results show the conversion of hydrotalcite phase into mixed metal oxide phase.…”

“…Different types of solid acid catalyst such as acidic cation‐exchange resin, Amberlyst‐15, Fe 3 O 4 ‐RGO‐SO 3 H, CrCl 3 ⋅6H 2 O/NaBr/ NaVO 3 ⋅2H 2 O and Fe 3 O 4 ‐SBA‐ SO 3 H are used for the dehydration of fructose to HMF. These solid acids in collaboration with metals or metal oxide (V‐based compound, Ru/HT, ZnFe 1.65 Ru 0.35 O 4 , VOHPO 4 and SBA‐15‐ biimidazole‐Ru) catalyst are employed for the selective oxidation of HMF to DFF . The applicability of such combined catalytic system is limited by the decomposition of fructose in the presence of molecular oxygen or air there by leading to a significant decrease in DFF yield.…”

In this work, a series of Co−Al hydrotalcites were synthesized in the molar ratio of 1:1(cat‐3), 2:1(cat‐4), 3:1(cat‐5). These synthesized Co−Al hydrotalcites were characterized by different characterization techniques such as XRD, XPS, FT‐IR, SEM, EDX, TGA, and N2 physical adsorption. The catalytic properties of the prepared Co−Al hydrotalcites in different molar ratio were investigated for the dehydration of fructose to 5‐hydroxymethylfurfural (HMF), and selective oxidation of the HMF into 2,5‐diformylfuran (DFF). The complete conversion of HMF led to 95% yield of DFF at 120 °C under 3 bar oxygen pressure in dimethyl sulfoxide (DMSO) for 6 h. DFF in the yield of 87% with 100% conversion of fructose could be achieved in a one pot and two‐step reaction using Co−Al calacite in ratio of 2:1(cat‐4). A 77% yield of DFF was obtained in one‐pot and one‐step reaction using the same hydrotalcite catalyst. A DFF yield of 59% was achieved in a one pot and one‐step reaction using air as oxidant. After completion of the reaction, the catalyst can be separate very easily and can be reused up to four times without any significant loss in its catalytic activity.

“…The rapid depletion of non‐renewable resources and the rising concerns about global warming moved the research towards the synthesis of transportation fuels and value added chemicals from renewable resources . 5‐hydroxymethylfurfural (HMF) is a platform molecule derived from dehydration of monosaccharides using homogenous and/or heterogeneous acid catalysts such as CrCl 3 + HCl, formic acid + H 2 SO 4 , Fe 3 O 4 ‐SBA‐SO 3 H, Amberlyst‐15, Hydrotalcites, acidic cation‐exchange resin, etc . Conversion of HMF into value‐added products such as 2,5‐dimethylfuran (DMF), 2,5‐furan‐dicarboxylic acid (FDCA), Maleic anhydride (MA), 2,5‐ diformylfuran (DFF), and levulinic acid is highly explored research area by various institution .…”

Hydrogenolysis of Biomass‐Derived 5‐Hydroxymethylfurfural to Produce 2,5‐Dimethylfuran Over Ru‐ZrO₂‐MCM‐41 Catalyst

In this work, an effective catalytic route for the selective hydrogenolysis of renewable biomass‐derived 5‐hydroxymethylfurfural (HMF) to high quality bio‐fuel 2,5‐dimethylfuran (DMF) was reported using Ru supported on ZrO2‐MCM‐41. The synthesized Ru supported on ZrO2‐MCM‐41 catalyst was characterized by different techniques such as XRD, BET surface area, XPS, SEM, TEM, EDX, TGA and TPD. Reaction parameters, like time, metal loading on ZrO2‐MCM‐41, catalyst loading, temperature, H2 pressure and solvent, were optimized for the conversion of HMF to DMF using prepared catalyst. The investigation performed in this study shows that Ru supported on ZrO2‐MCM‐41 is highly active and selective catalyst for effective transformation of the HMF into DMF in high yield and selectivity. With the use of 2 wt % Ru‐ZrO2‐MCM‐41 catalyst, 90% yield of DMF was obtained from HMF with very short reaction time of 1 h. The catalyst was recycled upto six time with slight decrease in yield after 4th cycle. A direct conversion of Fructose to DMF was also achieved in 53% yield using Amberlyst‐15 and 2%Ru‐ZrO2‐MCM‐41 combined catalyst in n‐butanol.

“…Few studies have reported the DFF synthesis based on a one-pot approach. Starting from fructose, two catalysts were used sequentially, fructose dehydration using an Amberlyst 15 catalyst and the subsequent oxidation of HMF using an Ru-based catalyst, and the DFF yield was 72.4% [7]. The Amberlyst 15 catalyst was used together with hydrotalcite-supported Ruthenium catalysts for the synthesis of DFF [8].…”

Abstract:In this work, a new kind of catalyst was prepared for synthesis of 5-hydroxymethylfurfural. Copper ions were incorporated into manganese oxide octahedral molecular sieves (K-OMS-2). The catalysts Cu-K-OMS-2 were characterized by measuring FTIR spectra, scanning electron microscope images, X-ray diffraction patterns, and temperature-programmed desorption (TPD) and temperature-programmed reduction (TPR) profiles. Thermogravimetric analysis (TGA) demonstrated that the stability of Cu-K-OMS-2 is almost the same as that of K-OMS-2. XRD patterns showed that introducing copper ions did not change the structure of K-OMS-2, but copper ions had an effect on the morphology of K-OMS-2 as illustrated by SEM images. TPD profiles demonstrated that both K-OMS-2 and Cu-K-OMS-2 possess basic and acidic sites, and Cu-K-OMS-2 has weak acidic sites. One-pot synthesis of 2,5-diformylfuran (DFF) from fructose was investigated under the catalysis of Cu-K-OMS-2 together with a commercial catalyst Amberlyst 15. The effect of reaction time and temperature on the DFF yield was investigated, and reaction temperature had an effect on the DFF yield. The effect of atomic ratio of Cu to Mn of Cu-K-OMS-2 on the DFF yield was also investigated. The DFF yield was improved 34.7% by Cu-K-OMS-2 in comparison to K-OMS-2, indicating the promotion effect of copper on the DFF yield. Consecutive use of Cu-K-OMS-2 demonstrated that after 6 cycles, the loss of DFF yield was 6.3%, indicating a good reusability of Cu-K-OMS-2.
