In the realm of supported metal catalysis, the metal component is usually present as nanoparticles dispersed on the surface of suitable metal oxides or on active carbon. Synthetic procedures are normally directed to the generation of size-controlled metal nanoclusters, whose circumstances become mandatory when reactions to be catalyzed are “structure sensitive”.In general, size control has been achieved by: directly manufacturing metal-oxide-supported catalysts;by the generation of kinetically stabilized metal nanoclusters in the liquid phase and subsequent transfer of the protected nanoclusters on to suitable supports; by generating metal nanoclusters inside isoporous inorganic materials such as mesoporous silicas. Herein, we report on three independent, convergent pieces of structural evidence of this template-controlled synthesis strategy to obtain size-controlled metal nanoclusters suitable for synthesizing resin-supported metal catalysts.
