A nickel phosphide nanoalloy supported by hydrotalcite demonstrated high catalytic activity for the hydrogenation of maltose, leading to efficient production of maltitol. Cooperative catalysis by the nanoalloy and the support played a key role in this process, enabling high-yield production even at ambient temperature. The catalyst showed promising performance in concentrated maltose solutions, highlighting its potential for sustainable production of maltitol.
Metal phosphide catalysts have attracted attention for organic synthesis owing to their stability and high activity. Nevertheless, metal-support interactions and support-boosted metal phosphide catalysis remain unexplored. Herein, we report the development of a hydrotalcite (HT: Mg6Al2CO3 (OH)(16)center dot 4(H2O))-supported nickel phosphide nanoalloy (nano-Ni2P/HT) that exhibits high activity for the hydrogenation of maltose, which is an important reaction for producing maltitol as a sweetener and food additive. The HT support drastically increased the catalytic activity of nano-Ni2P, allowing nano-Ni2P/HT to outperform conventional catalysts. Various spectroscopic studies revealed that cooperative catalysis by nano-Ni2P and HT plays a key role in the efficient hydrogenation of maltose. The cooperative catalysis enabled high-yield production of maltitol, even at ambient temperature. Furthermore, nano-Ni2P/HT was successfully recovered and reused while retaining its high activity and selectivity. Notably, nano-Ni2P/HT operated well in concentrated maltose solutions (>50 wt %), demonstrating that the high performance of this catalyst will pave the way for the efficient and sustainable production of maltitol.
