“…201 Amorphous alloys deposited on supports can further improve the activity and stability of a catalyst. 202 Materials with large surface area and porous structures such as mesoporous molecular sieves 125,203 or modified carbons 65 can be used as supports to disperse and stabilize metals and can provide acidic sites as multi-functional catalysts. It was found that Ni 2 P combinations, 180 and RuP combinations 65 as catalytic sites could obtain glucose conversions greater than 95% and sorbitol yields of up to 50%, when acid sites were loaded onto different supports.…”

“…Some new strategies have been proposed, such as the introduction of transition metal phosphides to regulate Ru electron transfer and to improve sorbitol yield. Qiu et al 65 designed Ru 2 P/C-SO 3 H catalysts to convert cellulose into sorbitol and obtained yields of 64% at 200 °C for 2 h reaction time. Xu et al 62 used defect-engineered MOFs supported Ru catalysts for glucose hydrogenation and obtained TOF values of over 2150 h −1 with catalyst stability being maintained for more than 10 cycles.…”

“…The hexose in hemicellulose is used in fermentation to produce fuel alcohol [ 62 ]. It also results in a reduction in sorbitol production [ 63 ]. Further, hemicellulose has been produced using xylose [ 64 ], xylitol [ 65 ], furfural [ 66 ], and feed yeast [ 67 ].…”

Insoluble dietary fiber is a macromolecular polysaccharide aggregate composed of pectin, glycoproteins, lignin, cellulose, and hemicellulose. All agricultural by-products contain significant levels of insoluble dietary fiber. With the recognition of the increasing scarcity of non-renewable energy sources, the conversion of single components of dietary fiber into renewable energy sources and their use has become an ongoing concern. The isolation and extraction of single fractions from insoluble dietary fiber is one of the most important recent research directions. The continuous development of technologies for the separation and extraction of single components is aimed at expanding the use of cellulose, hemicellulose, and lignin for food, industrial, cosmetic, biomedical, and other applications. Here, to expand the use of single components to meet the new needs of future development, separation and extraction methods for single components are summarized, in addition to the prospects of new raw materials in the future.

This work demonstrates that ruthenium phosphides (RuP2) are attractive catalysts for selective production of alditols by sugar hydrogenation. In our studies, carbon supported RuP2 with a ruthenium content of 5 wt.‐% led to the highest activity in xylose hydrogenation and to nearly 100 % yield for xylitol. ICP‐OES and XRD measurements revealed the stability of this novel RuP2/C catalyst under typical hydrogenation conditions (50 barH2, 120 °C) in aqueous phase. Furthermore, STEM‐EDX illustrated the close proximity of ruthenium and phosphorous on the catalyst site and the formation of nanoparticles in the size of 2‐4 nm. The novel catalyst system was successfully applied for the selective hydrogenation of further sugar substrates, including glucose, fructose, and disaccharides, such as cellobiose and sucrose. Here, the RuP2/C revealed its bifunctional acidic/metallic character, enabling in a tandem reaction the hydrolysis of disaccharides, directly followed by a selective hydrogenation to form sugar alcohols in high yield.
