Abstract

A ruthenium‐phosphorus (Ru‐P) amorphous alloy catalyst was prepared by chemical reduction of ruthenium(III) ions [Ru^3+^] with hypophosphite [H~2~PO~2~^−^] 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.
