Supramolecular nanocapsules as two-fold stabilizers of outer-cavity sub-nanometric Ru NPs and inner-cavity ultra-small Ru clusters

The synthesis of metallic nanoparticles with high surface area and known shape is of paramount importance to increase their catalytic properties. Here we show how a nanocapsule is able to control the formation of [Ru
