“…After optimization, the developed NiBO-10KH 2 PO 4 catalyst can efficiently convert glucose to sorbitol with almost quantitative yield under very mild reaction conditions (80 °C and 1 MPa of H 2 ). More importantly, in comparison with previous works, ,,− the NiBO-10KH 2 PO 4 catalyst avoids the use of high H 2 pressure (3–5 MPa) and high reaction temperature (120–160 °C) while providing good sorbitol yield with a short reaction time (Table S1).…”

Catalytic hydrogenation of carbohydrates over the Raney Ni catalyst is an important industrial process to produce valuable polyols. However, this process generally encounters challenges such as harsh reaction conditions, low catalytic activity, and catalyst deactivation. In this contribution, metallic nickel-rich nickel borides (NiBO-nKH2PO4) were successfully constructed via a simple chemical reduction method with potassium dihydrogen phosphate (KH2PO4) as the buffering agent and sodium borohydride (NaBH4) as the reducing reagent. Especially, the obtained NiBO-10KH2PO4 afforded quantitative sorbitol yield from the catalytic hydrogenation of glucose under mild reaction conditions within 1 h (80 °C and 1 MPa H2). Compared with the reported literature for the production of sorbitol from glucose, the developed NiBO-10KH2PO4 catalyst circumvents the use of a high hydrogen pressure and reaction temperature while delivering excellent catalytic performance and stability. Moreover, the experimental analysis demonstrated that the obtained nickel borides, with the assistance of KH2PO4, possessed abundant metallic nickel species, which favored the adsorption and activation of hydrogen molecules and thus largely promoted the hydrogenation of glucose. This work provides new insights into the rational design of practical nickel-based catalysts for the efficient catalytic hydrogenation of carbohydrates.

“…Niobium oxide supported Ru catalysts (5)Ru–Nb 2 O 5 ) are too reported for the conversion of glucose to sorbitol. 19 The said catalyst gave an 83% yield in the crystalline phase while the same catalyst gave a 28% sorbitol yield in the amorphous phase. Thus it requires reproducibility in the synthesis of the catalyst, which sometime might be an issue.…”

“…However, high temperatures resulted in the sintering of the catalyst, affecting catalytic activity, which in turn gave low glucose conversion. Silva et al [19] reported niobium oxide supported ruthenium catalyst, which exhibited high glucose conversion of 85 % and 99 % sorbitol selectivity when Nb 2 O 5 support was used in the crystalline form and when the amorphous phase of Nb 2 O 5 was used as support, the conversion and selectivities are 53 % and 55 %. Guo et al [20] performed glucose hydrogenation in the presence of Ru/ZSM-5, which gave 99.6 % glucose conversion and 99.2 % sorbitol selectivity.…”

A series of nickel hydroxyapatite catalysts were synthesized by the co‐precipitation method followed by calcination and reduction. These catalysts were employed for the aqueous phase hydrogenation of glucose to sorbitol. The Ni‐HAP catalyst with comparatively high surface area and acid‐base strength gave high sorbitol selectivity in 1 h. Ni‐HAP‐4 catalyst with moderate Ni (3.5 wt.%) content having smaller and highly dispersed nickel particles gives an excellent yield of sorbitol, 97% in 1h. The Ni‐HAP‐4 catalyst works well with other polar protic solvents. Different characterization techniques like XRD, TEM, SEM‐EDS, BET, NH3‐TPD, and CO2‐TPD were employed to analyze the Ni‐HAP‐4 catalyst.
