We report the hydrogenation catalytic activity application of molybdenum–ruthenium (MoRu) solid‐solution alloy nanoparticles (NPs) as catalysts for the hydrogenation of 1‐octene and 1‐octyne. The solid‐solution structure of MoRu NPs was confirmed through scanning transmission electron microscopy (STEM) coupled with energy‐dispersive X‐ray spectroscopy (EDX), and powder X‐ray diffraction (PXRD) measurement. The hydrogenation catalytic activity of these NPs toward 1‐octyne and 1‐octene in tetrahydrofuran (THF) was tested. The hydrogenation catalytic activity of Ru was enhanced by alloying with Mo at the atomic level. An electronic modification of Ru by a charge transfer from Mo to Ru, which could induce the change in the adsorption energy of reactants resulting in enhanced catalytic activity, was observed by X‐ray photoelectron spectroscopy.
