Pd/Ag Nanoparticles Prepared in Ionic Liquids as Model Catalysts for the Hydrogenation of Diphenylacetylene

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.
