Abstract

Abstract: The hydrogenation of D‐xylose is an industrially reliable method for preparing D‐xylitol, which is a commonly consumed chemical. Herein, we report the highly efficient and selective hydrogenation of D‐xylose to D‐xylitol in water over a hydrotalcite (HT: Mg6 Al2 CO3 (OH)16 ⋅ 4(H2 O))‐supported nickel phosphide nanoparticle catalyst (nano‐Ni2 P/HT). The HT support drastically increased the catalytic activity of the nano‐Ni2 P, enabling D‐xylitol synthesis under mild reaction conditions. Notably, the selective hydrogenation of D‐xylose to D‐xylitol proceeded even under 1 bar of H2 or at room temperature for the first time. The nano‐Ni2 P/HT catalyst also exhibited the highest activity among previously reported non‐noble metal catalysts, with a turnover number of 960. Moreover, the nano‐Ni2 P/HT catalyst was reusable and applicable to a concentrated D‐xylose solution (50 wt %), demonstrating its high potential for the industrial production of D‐xylitol. Abstract : The hydrogenation of D‐xylose to D‐xylitol proceeded efficiently over hydrotalcite‐supported nickel phosphide nanoparticles (nano‐Ni2 P/HT), which outperformed conventional catalysts and enabled D‐xylose hydrogenation even under 1 bar H2 or ambient temperature for the first time. Moreover, nano‐Ni2 P/HT was reusable, and operated well in a concentrated D‐xylose solution (50 wt %).
