Abstract Colloidal metal nanoparticles exhibit interesting catalytic properties for the hydrogenation of (hetero)arenes. Catalysts based on precious metals, such as Ru and Rh, promote this reaction efficiently under mild conditions. In contrast, heterogeneous catalysts earth‐abundant metals can selectively hydrogenate (hetero)arenes but require harsher Bimetallic that combine are materials to mitigate drawbacks each component. To end, RuNi bearing a phosphine ligand were prepared through decomposition [Ru(η 4 ‐C 8 H 12 )(η 6 10 )] [Ni(η ) 2 ] by at 85 °C. Wide angle X‐ray scattering confirmed bimetallic segregated structure, with Ni predominantly surface. Spectroscopic analyses revealed coordinated surface both suggesting, well, partial shell covering core. The RuNi‐based nanomaterials used in quinoline assess impact metallic composition stabilizing agent their performance.
