Carbon Nanoparticles on Magnetite: A New Heterogeneous Catalyst for the Oxidation of 5-Hydroxymethylfurfural (5-HMF) to 2,5-Diformoylfuran (DFF)

Nano Metal Oxide Frameworks (NOF): Development of New Heterogeneous Catalyst for the Synthesis of Furan Derivatives from Glucose

“…These furan derivatives are value-added components for the synthesis of biobased fuels and also in plastic technology. Surface modification of metal oxides has been successfully used in decomposing either fructose or glucose, and our present results were comparable to earlier reported results [16][17][18][19][20][21][22]. The significant byproducts formed during the dehydration of carbohydrates are levulinic acid and its derivatives [23,24].…”

“…The organic/inorganic hybrid materials have been explored in the dehydration of glucose by utilizing an imine framework to produce 5-hydroxymethyl furfural (HMF) and 2,5-diformylfuran (DFF), which are valuable intermediates in biofuel synthesis (Figure 3) [18][19][20].…”

The functional and synergetic optimization of the thermal-catalytic system for the selective oxidation of 5-hydroxymethylfurfural to 2,5-diformylfuran: a review

“…After adding strong bases like NaOH or KOH, the enhancement of HMF conversion decreased. 111,112 Similarly, Jaiswal et al 67 reported that no HMF conversion took place using Fe 3 O 4 /C without K 2 CO 3 . With the addition of K 2 CO 3 , 98.0% HMF conversion and 95.6% DFF selectivity were achieved under the O 2 atmosphere.…”

“…However, there was no significant difference in DFF adsorption compared to the blank experiment, meaning that the interaction between the DFF and catalyst was so weak that the catalyst can achieve high DFF selectivity. Jaiswal et al 67 reported an environment-friendly synthesis, using candle soot as the carbon substrate for loading Fe 3 O 4 . A hydrophobic carbon substrate was accommodated inside the magnetite and formed crystal defects, which was confirmed by Raman spectroscopy.…”

“…6). In addition, Jaiswal et al 49 observed the cooperative effect between carbon particles and Fe 3 O 4 nanoparticles in facilitating the selective oxidation of HMF to DFF. They demonstrated that the deposition of carbon particles derived from candle soot onto iron oxide surfaces resulted in a successful transformation with high selectivity, while Fe 3 O 4 nanoparticles alone were found to be negative for the desired transformation.…”
