We report on novel solid-solution alloy nanoparticles (NPs) of Ru and Cu that are completely immiscible even above melting point in bulk phase. Powder X-ray diffraction, scanning transmission electron microscopy, energy-dispersive measurements demonstrated atoms were homogeneously distributed the NPs. Ru0.5Cu0.5 NPs higher CO oxidation activity than fcc-Ru NPs, which known as one best monometallic catalysts.
