Allylic alcohols were hydrogenated using f to 3 nm diameter bimetallic Pd-Au dendrimer-encapsulated catalysts (DECs) [fi8]. Both alloy and core/shell Pd-Au nanoparticles were prepared. The catalytic hydrogenation of allyl alcohol was significantly enhanced in the presence of the alloy and core/shell Pd-Au nanoparticles as compared to mixtures of single-metal nanoparticles [fi8]. 

SnOi) are isolated and the interparticle distance varies from 5 to 100 nm (Fig. 5). Slightly above the percolation threshold the metal particles (Sn) form continuous filaments of varying diameter, but the maximal diameter never exceeds that of the single metal nanoparticle. Beyond the percolation threshold, the nanoparticles form aggregates located on the boundaries between the polymer globules.
