“…Inulin conversion was 100% for both catalysts. It can be seen that the selectivity to mannitol for 3% Ru-Fe 3 O 4 /MN270 is slightly higher than for the 5% Ru-Fe 3 O 4 /SiO 2 [162]. However, considering the lower ruthenium content in the polymer catalyst, the productivity of 3% Ru-Fe 3 O 4 /SiO 2 is almost twice as high.…”

“…For the first time, magnetic catalysts based on mesoporous silicon dioxide for this process were proposed by our group [162]. Testing a new magnetic catalyst based on HPS in the hydrolytic hydrogenation of inulin to mannitol was carried out under previously determined optimal conditions: 0.1167 mmol Ru per 1 g of inulin; 30 mL H 2 O; 150 • C; and P(H 2 ) 60 bar, 45 min.…”

Platform chemicals, also known as chemical building blocks, are substances that serve as starting materials for the synthesis of various value-added products, which find a wide range of applications. These chemicals are the key ingredients for many fine and specialty chemicals. Most of the transformations of platform chemicals are catalytic processes, which should meet the requirements of sustainable chemistry: to be not toxic for humans, to be safe for the environment, and to allow multiple reuses of catalytic materials. This paper presents an overview of a new class of heterogeneous catalysts based on nanoparticles of catalytically active metals stabilized by a polymer matrix of hypercrosslinked polystyrene (HPS). This polymeric support is characterized by hierarchical porosity (including meso- and macropores along with micropores), which is important both for the formation of metal nanoparticles and for efficient mass transfer of reactants. The influence of key parameters such as the morphology of nanoparticles (bimetallic versus monometallic) and the presence of functional groups in the polymer matrix on the catalytic properties is considered. Emphasis is placed on the use of this class of heterogeneous catalysts for the conversion of plant polysaccharides into polyols (sorbitol, mannitol, and glycols), hydrogenation of levulinic acid, furfural, oxidation of disaccharides, and some other reactions that might be useful for large-scale industrial processes that aim to be sustainable. Some challenges related to the use of HPS-based catalysts are addressed and multiple perspectives are discussed.

“…The mildly acidic reaction conditions prevent degradation of the carbon framework (e.g., retro-aldol reactions), which usually occurs under basic conditions. [27] Furthermore, the hydrolytic hydrogenation of inulin (4) represents the first homogeneous and selective synthesis of 3 a from 4, [15,29] exemplifying the systems tolerance towards water. Collectively, this work showcases that the wellestablished "Noyori chemistry" has still not found its limitations and, again, proves to be a highly useful methodology in an industrial context.…”

Selective and Scalable Synthesis of Sugar Alcohols by Homogeneous Asymmetric Hydrogenation of Unprotected Ketoses

Sugar alcohols are of great importance for the food industry and are promising building blocks for bio-based polymers. Industrially, they are produced by heterogeneous hydrogenation of sugars with H 2 , usually with none to low stereoselectivities. Now, we present a homogeneous system based on commercially available components, which not only increases the overall yield, but also allows a wide range of unprotected ketoses to be diastereoselectively hydrogenated. Furthermore, the system is reliable on a multi-gram scale allowing sugar alcohols to be isolated in large quantities at high atom economy.

“…Therefore, developing an easy‐to‐separate solid acid catalyst is necessary in the conversion of cellulose into biofuels or platform chemicals. A magnetically separable catalyst has recently received considerable attention because of the easy separation from the reaction mixture by a permanent magnet, which facilitates the repetitive use of the catalyst and is beneficial in saving energy and decreasing the cost of the target product . Although the magnetic carbon‐based solid acid showed a promising advantage in the hydrolysis of biomass, the synthetic route usually was a complicated and time‐consuming process.…”

BACKGROUND: Effective cellulose hydrolysis has a huge potential for producing high value-added biomass-based platform chemicals, such as glucose, hydroxymethylfurfural, levulinic acid, and total reducing sugars (TRS). Particularly, a magnetic multifunctional solid acid catalyst (Fe 3 O 4 /Cl-MCMB-SO 3 H) was synthesized by loading the active groups on the magnetic mesocarbon microbead (MCMB) derived from the co-calcination of coal tar pitch and ferroferric oxide, which was applied as a catalyst in the conversion of cellulose into TRS. RESULTS: Given the superior properties of MCMB, a novel magnetic MCMB-based solid acid with cellulose-binding domain (-Cl group) and catalytic domain (-SO 3 H group) was successfully prepared. Results indicated that this catalyst exhibited superior catalytic activity, recyclability and regenerability, and easy separation from the reactant. The acidic densities of -SO 3 H and -Cl in Fe 3 O 4 /Cl-MCMB-SO 3 H reached 1.77 and 1.32 mmol/g, respectively. The 68.6% TRS yield can be obtained from cellulose at 140 ∘ C for 3 h in distilled water by using Fe 3 O 4 /Cl-MCMB-SO 3 H as the catalyst.The TRS yield still reached 61.1% after the catalyst was used six times. Importantly, through catalyst regeneration, the -SO 3 H density and TRS yield still reached 1.69 mmol/g and 67.3%, indicating that the catalyst exhibited excellent regenerability. CONCLUSION: Such multifunctional magnetic catalyst would be a promising catalyst in the conversion of cellulose into biofuels, which was attributed to the efficient catalytic performance, magnetism, and excellent recyclability and regenerability.
