“…Catalyst prepared by acid functionalization on mesoporous carbon/silica material via infiltration, carbonization, and sulfonation sequence gave slightly lower yield (70%) . It should be noted that magnetically separable acid catalysts (i.e., Fe 3 O 4 @Si/Ph-SO 3 H), chromium-exchanged hydroxyapatite γ-Fe 2 O 3 (γ-Fe 2 O 3 @HAP-Cr), and Fe 3 O 4 @C–SO 3 H also exhibited remarkable (82–89%) yield at 110–120 °C for 3–4 h in DMSO.…”

The replacement of fossil resources that currently provide more than 90% of our energy needs and feedstocks of the chemical industry in combination with reduced emission of carbon dioxide is one of the most pressing challenges of mankind. Biomass as a globally available resource has been proposed as an alternative feedstock for production of basic building blocks, which could partially or even fully replace the currently utilized fossil-based ones in well-established chemical processes. The destruction of lignocellulosic feed followed by oxygen removal from its cellulose and hemicellulose content by catalytic processes results in the formation of initial platform chemicals (IPCs). However, their sustainable production strongly depends on the availability of resources, their efficient or even industrially viable conversion processes, and replenishment time of feedstocks. Herein, we overview recent advances and developments in catalytic transformations of the carbohydrate content of lignocellulosic biomass to IPCs (i.e., ethanol, 3-hydroxypropionic acid, isoprene, succinic and levulinic acids, furfural, and 5-hydroxymethylfurfural). The mechanistic aspects, development of new catalysts, different efficiency indicators (yield and selectivity), and conversion conditions of their production are presented and compared. The potential biochemical production routes utilizing recently engineered microorganisms are reviewed, as well. The sustainability metrics that could be applied to the chemical industry (individual set of sustainability indicators, composite indices methods, material and energy flow analysis-based metrics, and ethanol equivalents) are also overviewed as well as an outlook is provided to highlight challenges and opportunities associated with this huge research area.

“…Yao et al designed a magnetically recoverable carbonaceous material catalyst, which could be recovered by an external magnetic field after reaction. [34] Nevertheless, there was also a certain catalyst loss and high cost of industrial production in the recovery process. It was important to develop a more efficient catalytic system for the industrial production of 5-HMF with lower cost and better performance.…”

Millimeter size γ‐Al2O3 beads were prepared by alginate assisted sol–gel method and grafting organic groups with propyl sulfonic acid and alkyl groups as functionalized γ‐Al2O3 bead catalysts for fructose dehydration to 5‐hydroxymethylfurfural (5‐HMF). Experiment results showed that the porous structure of γ‐Al2O3 beads was favorable to the loading and dispersion of active components, and had an obvious effect on the properties of the catalyst. The lower calcination temperature of γ‐Al2O3 beads increased the specific surface area, the hydrophobicity and the activity of catalysts. Competition between the reaction of alkyl groups and ‐SH groups with surface hydroxyl during the preparation process of the catalyst influenced greatly the acid site densities, hydrophobic properties and activity of the catalyst. With an increase in the alkyl group chain, the hydrophobicity of catalysts increased obviously and the activity of the catalyst was enhanced. The most hydrophobic catalyst C16‐SO3H‐γ‐Al2O3–650°C exhibited the highest yield of 5‐HMF (84%) under the following reaction conditions: reaction medium of dimethylsulfoxide/H2O (V/V, 4:1), catalyst amount of 30 mg, temperature of 110°C and reaction time of 4 hr.

“…Metal-Organic Frameworks (MOFs) were also applied as carbon groups for preparing the sulfonic acid functionalized catalyst, which exhibited highly considerable catalytic for etherification of HMF to EMF (71%) or esterification of HMF to ethyl levulinate (81%) in ethanol medium [61]. In addition, glucose [62], wheat straw [63], carbon nanomaterial [64], lignosulfonate [65] used as carbon groups were studied, respectively. The specific structures and chemical properties of carbonyl sulfonated solid acids were similar while the preparation methods and starting materials acted as carbon groups were different, which lead to a relatively high catalytic for the conversion of fructose-based carbohydrates to EMF.…”

Biomass-derived 5-ethoxymethylfurfural (EMF) with excellent energy density and satisfactory combustion performance holds great promise to meet the growing demands for transportation fuels and fuel additives to a certain extent. In this review, we summarized the relative merits of the EMF preparation from different feedstocks, such as platform chemicals, biomass sugars and lignocellulosic biomass. Advances for EMF synthesis over homogeneous (i.e. inorganic acids and soluble metal salts), heterogeneous catalysts (i.e. zeolites, heteropolyacidbased hybrids, sulfonic acid-functionalized catalysts, and others) or mixed-acid catalysts were performed as well. Additionally, the emerging development for the EMF production was also evaluated in terms of the different solvents system (i.e. single-phase solvents, biphasic solvents, ionic liquids, and deep eutectic solvents). It is concluded with current challenges and prospects for advanced biofuel EMF preparation in the future.
