Gold as a modifier of metal nanoparticles: effect on structure and catalysis

Author affiliations

Abstract

Bimetallic gold based catalysts have been prepared using a sol immobilisation technique. Despite a very similar metal dispersion, different structures are revealed depending on the second metal, with alloyed systems being preferred in the case of Pd, Pt and Cu, and core–shell in the case of Ru. A positive synergistic effect between the metals has been revealed only in the cases of Pd and Cu in the oxidation of benzyl alcohol. AuPd/C has been also studied in the hydrogenation of benzaldehyde where the bimetallic catalyst revealed a different selectivity compared to the monometallic counterpart.
