“…Figure S1A shows the small-angle XRD patterns of thus-synthesized functionalized and pure SBA-15 materials. All samples presented well-resolved reflections that could be indexed as the (100), (110), and (200) planes corresponding to the typical P6mm space group, which were in line with those of the bare SBA-15 support reported in a previous publication . It was implied that the two-dimensional (2D) hexagonal mesostructures of the pure SBA-15 material in the investigated samples were retained even after undergoing incorporation of only Zn atoms or both Zn atoms and organic −SO 3 H groups.…”

Catalytic production of structured phospholipids (SPLs) containing short-chain fatty acids (SCFAs) in an efficient heterogeneous manner is of great importance from the standpoint of food engineering. Herein, a bifunctionalized sulfonated Zn-SBA-15 catalyst was studied for SPL synthesis through interesterification of soybean lecithin with ethyl propionate or methyl butyrate. Various characterization techniques such as pyridine Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and ultraviolet−visible diffuse reflectance spectroscopy were conducted to determine the physicochemical properties, so as to build the possible structure−reactivity relationship of the catalyst. In screening tests with commercial Amberlyst-15 or other SBA-15-type materials, the as-prepared sample showed promising catalytic performance probably owing to its mesoporous structure and cooperative role of Bronsted and Lewis acid sites. Notably, the sample was easily separated and recycled without obvious deactivation. In general, the investigated catalyst was regarded as one of the promising alternatives to otherwise expensive biocatalysts for SCFA-containing SPL production.

“…In DMSO-toluene-water (1:8:2, v:v:v) containing NaCl (4% w/v), 2 wt% corn straw, and 10 wt% SO 4 2− /Sn-TRP catalyst (mass ratio and substrate), the yield of furfural reached 77.8% at 190 • C in 3 h [37]. In toluene-water (1:2. v:v), AAO@Al/FDU-5-7.5E-SO 3 H catalyzed xylose to produce furfural in the yield of 66.2% at 160 • C in 4 h [38]. The solid lignin-based catalyst LC-1S was used to transform xylose into furfural in the yield of 65% at 175 • C within 3 h in methyl isobutyl ketone (MIBK) [39].…”

Valorization of Waste Lignocellulose to Furfural by Sulfonated Biobased Heterogeneous Catalyst Using Ultrasonic-Treated Chestnut Shell Waste as Carrier

et al. 2021

Recently, the highly efficient production of value-added biobased chemicals from available, inexpensive, and renewable biomass has gained more and more attention in a sustainable catalytic process. Furfural is a versatile biobased chemical, which has been widely used for making solvents, lubricants, inks, adhesives, antacids, polymers, plastics, fuels, fragrances, flavors, fungicides, fertilizers, nematicides, agrochemicals, and pharmaceuticals. In this work, ultrasonic-treated chestnut shell waste (UTS-CSW) was utilized as biobased support to prepare biomass-based heterogeneous catalyst (CSUTS-CSW) for transforming waste lignocellulosic materials into furfural. The pore and surface properties of CSUTS-CSW were characterized with BET, SEM, XRD, and FT-IR. In toluene–water (2:1, v:v; pH 1.0), CSUTS-CSW (3.6 wt%) converted corncob into furfural yield in the yield of 68.7% at 180 °C in 15 min. CSUTS-CSW had high activity and thermostability, which could be recycled and reused for seven batches. From first to seventh, the yields were obtained from 68.7 to 47.5%. Clearly, this biobased solid acid CSUTS-CSW could be used for the sustainable conversion of waste biomasses into furfural, which had potential application in future.

“…Hu et al obtained by these means of several mesoporous sulfonated catalysts of the FDU and SBA type. Their best catalyst (FDU-5-7.5E-SO 3 H) was able to convert almost all xylose (97%), rendering up to 81% yield to furfural at 160 • C. However, again, on successive reaction cycles, the yield to furfural decreased down to 60% after the fifth cycle [78].…”

Catalytic Processes from Biomass-Derived Hexoses and Pentoses: A Recent Literature Overview

2018

Biomass is a plentiful renewable source of energy, food, feed and chemicals. It fixes about 1–2% of the solar energy received by the Earth through photosynthesis in both terrestrial and aquatic plants like macro- and microalgae. As fossil resources deplete, biomass appears a good complement and eventually a good substitute feedstock, but still needs the development of relatively new catalytic processes. For this purpose, catalytic transformations, whether alone or combined with thermal ones and separation operations, have been under study in recent years. Catalytic biorefineries are based on dehydration-hydrations, hydrogenations, oxidations, epimerizations, isomerizations, aldol condensations and other reactions to obtain a plethora of chemicals, including alcohols, ketones, furans and acids, as well as materials such as polycarbonates. Nevertheless, there is still a need for higher selectivity, stability, and regenerability of catalysts and of process intensification by a wise combination of operations, either in-series or combined (one-pot), to reach economic feasibility. Here we present a literature survey of the latest developments for obtaining value-added products using hexoses and pentoses derived from lignocellulosic material, as well as algae as a source of carbohydrates for subsequent transformations.
