The preparation of bimetallic Pd/Ag‐based model catalysts is addressed to study the promotional effects of Ag doping in the liquid‐phase semi‐hydrogenation of diphenylacetylene. The precursor concept is employed where colloidal bimetallic Pd/Ag nanoparticles are initially synthesized and then used as well‐defined building units for catalyst preparation. This approach allows for tuning the composition of the nanoparticles independently with the two metals co‐localized to a fine extent. Size and composition of the nanoparticles are preserved after immobilizing them on a carbon support.
