“…5‐Ethoxymethylfurfural (EMF), which is accessible through the etherification of HMF with ethanol, has recently been identified as a promising additive for transportation fuels due to its high energy density (30.3 MJ L −1 , which is higher than that of ethanol and close to that of gasoline and diesel), as well as positive results accomplished in terms of the reduction of SO x and soot emissions . Although a high yield of EMF was achieved through the etherification of HMF with ethanol over an acid catalyst, the choice of HMF as a substrate is not industrially preferred due to the high price of HMF and/or difficulties in isolating HMF in good yields.…”

Shifting from petroleum‐based resources to inedible biomass for the production of valuable chemicals and fuels is one of the significant aspects in sustainable chemistry for realizing the sustainable development of our society. Various renowned biobased platform molecules, such as 5‐hydroxymethylfurfural, furfural, levulinic acid, and lactic acid, are successfully accessible from the transformation of biobased sugars. To achieve the specific reaction routes, heterogeneous nanoporous acidic materials have served as promising catalysts for the conversion of bio‐sugars in the past decade. This Review summarizes advances in various nanoporous acidic materials for bio‐sugar conversion, in which the number of carbon atoms is variable and controllable with the assistance of the switchable structure of nanoporous materials. The major focus of this Review is on possible reaction pathways/mechanisms and the relationships between catalyst structure and catalytic performance. Moreover, representative examples of catalytic upgrading of biobased platform molecules to biochemicals and fuels through selective C−C cleavage and coupling strategies over nanoporous acidic materials are also discussed.

“…Among these starting materials, fructose is always being regarded as a desirable candidate because the formation of 5‐HMF is more facile in its dehydration . Besides, it has been generally accepted that the process of fructose dehydration into 5‐HMF is mainly catalyzed by Brönsted acid sites in catalysts . Hence, it is essential to develop highly efficient catalysts with abundant Brönsted acid sites for production of 5‐HMF via dehydration of fructose …”

An environmentally benign carbonaceous solid acid was synthesized from microalgae residue discarded after biodiesel production. Thereafter, the as‐synthesized carbonaceous solid acid was used for catalytic dehydration of fructose into 5‐hydroxymethylfurural (5‐HMF). Various techniques such as X‐ray diffraction, N2 adsorption‐desorption, scanning electron microscopy, Fourier transform infrared, Raman, X‐ray photoelectron spectroscopy and pyridine adsorption etc were conducted to elucidate the structural and acidic properties of the solid acid so as to build the structure‐performance relationship. The results suggested that large amounts of ‐SO3H, phenolic ‐OH and ‐COOH groups were grafted onto the investigated material and most of the surface acid sites were assigned to strong Brönsted acid sites. In screening tests with other commercial catalysts, the as‐prepared sample presented excellent catalytic activity with 76.65±2.53% yield of 5‐HMF under aqueous conditions. The dehydration of fructose in dimethyl sulfoxide‐water biphasic system was also tested, affording the 5‐HMF yield as high as 93.84±1.12%. This work provides an efficient and selective solid acid from biodiesel waste and might shed light on an alternative catalyst for highly efficient production of 5‐HMF instead of homogeneous catalysts.

“…However, several drawbacks, such as the difficulty of catalyst recovery and the generation of acid wastes, limited the application of these homogeneous catalysts for the production of HMF at commercial scales . In recent years, a wide range of heterogeneous catalysts, including metal oxides, metal phosphates, zeolites, acid‐functionalized carbon, acid‐functionalized silicon dioxide (SiO 2 ), ion‐exchange resins, and metal–organic frameworks, have been studied for the synthesis of HMF, most of which have proven to have excellent activity and good reusability …”

BACKGROUND 5‐Hydroxymethylfurfural (HMF) is an important platform chemical that can be generated from biomass using catalysts and used for the production of biofuels and biobased polymers. RESULTS In this study, a novel magnetically‐recoverable catalyst (Fe3O4@SiO2@TiO2−HPW) was synthesized for the first time by immobilizing H3PW12O40 (HPW) on the surfaces of SiO2 and TiO2‐coated Fe3O4 nanoparticles. A number of techniques, including inductively coupled plasma (ICP) spectroscopy, transmission electron microscopy (TEM), Fourier‐transform infrared (FTIR) spectroscopy and nitrogen (N2) adsorption–desorption analysis, were used to characterize the catalyst. Results showed that the catalyst had a porous structure and the Keggin structure of HPW on the surface of the catalyst was well‐preserved. The catalyst was then used for the syntheses of HMF from fructose and inulin using dimethyl sulfoxide (DMSO) as a solvent, and the influences of reaction temperature and reaction time were investigated. Results showed that HMF yields obtained from fructose and inulin reached 83% and 54%, respectively. After reaction, the catalyst could be easily separated from reaction mixture using an external magnet, and the catalytic activity of the catalyst was well‐preserved after more than five reuses. CONCLUSION This magnetically‐recoverable catalyst is efficient not only for the syntheses of HMF from fructose and inulin, but also potentially for the one‐step production of HMF from inulin‐containing biomass, and its magnetic property may overcome the difficulty of catalyst separation from the insoluble biomass residues. © 2019 Society of Chemical Industry
