      abstract     = {Bimetallic manganese–ruthenium nanoparticles of defined
                      Mn:Ru ratios were prepared on an imidazolium-based supported
                      ionic liquid phase. Characterization of the resulting
                      Mn$_x$Ru$_{100–x}$@SILP materials by electron microscopy
                      evidenced the formation of small (1.3–3.6 nm) and
                      well-dispersed nanoparticles (NPs) containing Mn and Ru in
                      the expected ratios. X-ray absorption spectroscopy (XAS)
                      studies revealed that no significant levels of alloying
                      occurred in these NPs that contain mainly oxidized Mn
                      species and metallic Ru, consistent with the immiscibility
                      of the two metals and the high oxophilicity of Mn. The
                      hydrogenation performance of Mn$_x$Ru$_{100–x}$@SILP
                      materials was probed using benzylideneacetone as model
                      substrate containing three distinct reducible moieties.
                      Albeit the two metals are present in distinct phases, the
                      Mn:Ru ratio was found to have a strong impact on activity
                      and selectivity with trends similar to what was previously
                      reported for alloyed Fe$_x$Ru$_{100–x}$@SILP and
                      Co$_x$Ru$_{100–x}$@SILP catalysts. In particular, a sharp
                      switch of 6-membered aromatic ring hydrogenation between
                      Mn$_{15}$Ru$_{85}$ (full ring hydrogenation) and
                      Mn$_{25}$Ru$_{75}$ (no ring hydrogenation) was observed.
                      These results demonstrate that alloying is not a requirement
                      to observe synergistic effects from the combination of 3d
                      metals and noble metals in NPs, opening new opportunities
                      for the development of bimetallic catalysts for selective
                      hydrogenation.},
