 Abstract: Bimetallic iron-ruthenium and cobalt-ruthenium nanoparticles with systematic variations in the Fe:Ru and Co:Ru ratios are prepared following an organometallic approach and immobilized on an imidazolium-based supported ionic liquid phase (SILP). Resulting MxRu100-x@SILP materials are characterized by electron microscopy, X-ray diffraction and X-ray absorption spectroscopy, confirming the formation of small, well-dispersed and alloyed zero-valent bimetallic nanoparticles. A systematic comparison of the performances of FexRu100−x@SILP and CoxRu100−x@SILP catalysts is made using the hydrogenation of benzilideneacetone as model reaction. The M:Ru ratio is found to have a critical influence on activity and selectivity, with clear synergistic effects arising from the combination of the noble and 3d metals. CoxRu100−x@SILP catalysts are significantly more reactive to reach a given selectivity at a systematically higher content of the 3d metal as compared to the FexRu100−x@SILP catalysts, evidencing a remarkable influence of the nature of the “diluting” 3d metal on the overall performance of the MxRu100−x@SILP catalysts.
