Preparation of a Ru‐Nanoparticles/Defective‐Graphene Composite as a Highly Efficient Arene‐Hydrogenation Catalyst

A right mix‐up! A facile approach is reported that enables the in situ production of fine Ru nanoparticles ( d ≈3 nm) on graphene oxide. The as‐obtained composite shows superior catalytic activity and stability for the hydrogenation of arenes.
