Herein we present the preparation of water soluble, N-heterocyclic carbene-stabilized AuPd alloy nanoparticles by a straightforward ligand exchange process. Extensive analysis revealed excellent size retention and stability over years in water. The alloy nanoparticles were applied as biomimetic catalyst for the aerobic oxidation of D-glucose, in which monometallic Au and Pd nanoparticles showed no or negligible activity. The alloy nanoparticles were further applied as titania-supported heterogeneous catalysts for the mild hydrogenation of nitroarenes and in the semihydrogenation of 1,2-diphenylacetylene with a solvent-dependent selectivity switch between E- and Z-stilbene.
