The hydrogenation of carbohydrates to polyols is an industrially important process, but it requires air-unstable, non-noble metal catalysts with low activity and harsh reaction conditions. Herein, we report a hydrotalcite (HT)-supported nickel phosphide nanoparticle (nano-Ni P/HT) that exhibits both air stability and high activity for the selective hydrogenation ofd-glucose tod-sorbitol in water. The nano-Ni P/HT catalyst providesd-sorbitol in excellent yield with >99% selectivity under mild reaction conditions, and is the first non-noble metal catalyst that can operate under just 1 bar of H or at ambient temperature. This high-performance nano-Ni P/HT catalyst is significantly different from conventional Ni(0) and NiO nanoparticles and Raney catalysts, which result in almost no production ofd-sorbitol, demonstrating the unique catalysis of nano-Ni P/HT. Furthermore, nano-Ni P/HT shows the highest activity among those reported for non-noble metal catalysts. The nano-Ni P/HT catalyst can also be reused without sacrificing its high activity and selectivity. Additionally, the successful transformation of a concentratedd-glucose solution (50 wt%) tod-sorbitol has been achieved. This is the first example of an air-stable, highly active, and reusable non-noble metal catalyst that can replace conventional catalysts used ford-sorbitol production, thus providing a cheap, green, and sustainable route for this process. 2 2 2 2 2 2 2
