Abstract

Oh my Gold! Gold atoms stabilise catalytically active palladium nanoparticles when engaged in an alloy heterogenised on carbon. The increased durability makes the Pd-Au/C catalyst more recyclable than the gold-free Pd/C catalyst for the Sonogashira reaction.

Keywords: Pd-Au alloys; Sonogashira reaction; electrochemistry; heterogeneous catalysis; palladium nanoparticles.
