Summary: A catalytic system using micro-reactors composed of CTAB was developed to convert high-concentration fructose into HMF. The formation of humins was effectively restrained, resulting in high HMF yield and TOF. This work provides valuable guidance for designing effective catalytic systems for future HMF biorefineries.

Summary: This study proposes a low-temperature production of 5-hydroxymethylfurfural (HMF) from fructose in ternary deep eutectic solvents (TerDESs) consisting of choline chloride (ChCl), ethylene glycol (EG), and maleic acid (MalA). Experimental results show that a fructose conversion of 99.9% and an HMF yield of 87.3% can be achieved in TerDES with ChCl/EG/MalA = 3:1:1 at 70 degrees C in 30 min. The synergistic effects of ChCl and EG in TerDES contribute to the enhanced dehydration of fructose under mild conditions. The recycling results of TerDES demonstrate stable yields of HMF within five reuse cycles. This research provides an efficient solution for green and sustainable high-yield HMF production.

Summary: Understanding the formation pathways of soluble humins in the fructose-to-HMF dehydration catalyzed by solid acid is critical for the design of efficient heterogeneous catalysts for HMF synthesis. This study revealed three representative formation paths of soluble humins and identified the types of acids that contribute to each path. The optimal catalyst was found to have a low density ratio of medium-strong to weak Bronsted acids and a low density of strong Lewis acids, effectively inhibiting humin formation. These findings emphasize the importance of rational catalyst design to minimize undesired humin formation in HMF biorefinery.

Summary: In this study, a cheap and efficient deep eutectic solvent was developed for the conversion of glucose and other carbohydrates to 5-Hydroxymethylfurfural (HMF). The high HMF yields achieved from various carbohydrates make this system a promising method for HMF synthesis. The identification of the active species in the solvent provides a basis for future research on the dehydration mechanisms.

Summary: The direct conversion of glucose to HMF was studied using MOF as catalysts and POM as a co-catalyst. Two routes were investigated and it was found that the reactions with MIL-53(Al) and MIL-101(Cr) catalysts produced the highest yield of HMF. Stability tests on the POM@MOF catalysts showed that MIL-53(Al) and Hsiw@ MIL-101(Cr) can be reused but with a progressive loss in HMF yield.

Summary: The supercritical CO2-subcritical H2O system can serve as a reaction solvent for organic synthesis, promoting the conversion of organic compounds due to enhanced formation of carbonic acid and ionization of water under elevated pressures and temperatures. The biphasic nature of the system allows for extraction of less polar products from aqueous solutions. Experimental results showed higher yields and selectivity in converting glucose to HMF in this system, with potential mechanisms determined through quantum calculations.

Summary: Metal organic framework UiO-66 was studied as a heterogeneous catalyst for glucose conversion, with modified UiO-66 showing higher isomerisation activity. Replacing 50% of the linkers with sulfonate-containing linkers resulted in increased isomerisation activity, while the introduction of naphthalene-dicarboxylate linkers improved fructose selectivity.

Summary: The process of transforming carbohydrates into platform substances using nickel modified zeolite catalysts has been studied, with 5NiHM and 5NiHZSM-5 showing superior performance in glucose conversion. The balance between catalyst acidity and textural properties plays a key role in this transformation process. Nickel-containing zeolite ZSM-5 and M are promising catalysts for glucose conversion, with potential trends in related research discussed.

Summary: This study investigates the role of Lewis/Bronsted acid sites in glucose dehydration, finding that catalyst activity is dependent on catalyst composition. Lewis acid promotes isomerization, while Bronsted acid directly dehydrates glucose to HMF. Furthermore, the study includes kinetic modeling of the reactions and their comparison with empirical observations.
