“…of fructose and glucose proceeds via ring forms rather than a linear keto (aldehyde) structure. Meanwhile, Beenackers et al [19] showed that, upon adsorption of glucose on metals, an ionized species is generated (i.e., glucose anion) which was susceptible to attack by hydrogen adsorbed dissociatively on the neighboring metal sites, initiating the reaction. Accordingly, the adsorption and hydrogenation of the maltose molecule on Ru-based amorphous alloy catalysts could be described in the following model schematized in Scheme 3.…”

A ruthenium-phosphorus (Ru-P) amorphous alloy catalyst was prepared by chemical reduc-À ] in aqueous solution and was applied to the liquid-phase hydrogenation of maltose. In comparison with other reference catalysts, Ru-P showed significant activity as evident in the order: Ru-P > Ru-B @ Ni-P > Co-P @ Raney Ni. Furthermore, this catalyst was also found to be more durable during this hydrogenation process. Special emphasis was laid on a comparative study of Ru-P and Ru-B catalysts to get an insight into the excellent catalytic performances of Ru-P.

“…(ii) Electronic effect: Makkee et al [36] confirmed that the hydrogenation of fructose and glucose proceeds via a ring form rather than a linear keto (aldehyde) structure. Meanwhile, Beenackers et al [37] showed that, upon the adsorption of glucose on metals, an ionized species is generated (i.e., glucose anion), which was susceptible to attack by hydrogen adsorbed dissociatively on the neighboring metal sites, initiating the reaction. The aforementioned XPS spectra demonstrated the strong electronic interaction between Ru and B in the Ru-B amorphous alloy, making Ru electron-enriched while B electron-deficient.…”

Monodisperse Ru-B amorphous alloy catalysts were synthesized by ultrasound-assisted chemical reduction of (NH 4 ) 2 RuCl 6 with BH 4 -. With the characterization of X-ray diffraction (XRD), selective area electronic diffraction (SAED), X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC), and transmission electron microscopy (TEM), the resulting Ru-B nanoparticles were identified to be amorphous alloys ranging in size from 2.4 to 4.9 nm. During liquid-phase maltose hydrogenation, the as-synthesized Ru-B catalyst was extremely active compared to the regular Ru-B obtained via the reduction of RuCl 3 with BH 4 -. The Ru-B sample prepared under ultrasonication with 60 W was proven to be the most active catalyst. Its catalytic activity was nearly 11 times that of industrial Raney Ni, and could be used repetitively for more than six times without significant deactivation.

“…the pH to alkaline, fructose usually ionizes when the pK is 11.99 to 12.5 (9); it also has the advantage of being more soluble than other sugars; here fructose is used as reducing and stabilizing agent. The synthesis of the gold nanoparticles described in this work is easy and convenient as is carried out at room temperature and atmospheric pressure.…”
