abstract = {The search for new ligands capable of modifying the metal nanoparticle (MNP) catalytic behavior is of
increasing interest. Herein we present the first example of RuNPs stabilized with non-planar heptagoncontaining
saddle-shaped nanographenes (Ru@1 and Ru@2). The resemblance to graphene-supported
MNPs makes these non-planar nanographene-stabilized RuNPs very attractive systems to further
investigate graphene–metal interactions. A combined theoretical/experimental study allowed us to
explore the coordination modes and dynamics of these nanographenes at the Ru surface. The curvature
of these saddle-shaped nanographenes makes them efficient MNP stabilizers. The resulting RuNPs were
found to be highly active catalysts for the hydrogenation of aromatics, including platform molecules
derived from biomass (i.e. HMF) or liquid organic hydrogen carriers (i.e. N-indole). A significant ligand
effect was observed since a minor modification on the hept-HBC structure (C]CH2 instead of C]O)
was reflected in a substantial increase in the MNP activity. Finally, the stability of these canopied RuNPs
was investigated by multiple addition experiments, proving to be stable catalysts for at least 96 h.},
