This critical review summarizes recent advances on the preparation, characterization and application of Aubased bimetallic Au-M catalysts. Particularly bimetallic Au-Pd, Au-Pt and Au-Ag catalysts have been emphasized. The diversity of the structure and combination of these bimetallic Au-M catalysts leads to various catalytic performances in, i.e., oxidation, hydrogenation, electrocatalytic, and photocatalytic reactions. The promotional effects of Au have been discussed by its electronic and geometric modifications of active metals. Efforts on controlling the structure (morphology, particle size and growth of crystalline) of supported bimetallic Au-M catalysts via advanced synthetic approaches have been elaborated. An overview on the challenges and opportunities for future research toward the understanding of catalytic chemistry of gold-based bimetallic systems has also been presented along with the descrption of few of the recent patents. Keywords: Bimetallic catalyst, nanoalloy, gold-based catalysts, Au-Pd, Au-Cu, Au-Ag.

Heterogeneous bimetallic catalysts have broad applications in industrial processes, but achieving a fundamental understanding on the nature of the active sites in bimetallic catalysts at the atomic and molecular level is very challenging due to the structural complexity of the bimetallic catalysts. Comparing the structural features and the catalytic performances of different bimetallic entities will favor the formation of a unified understanding of the structure-reactivity relationships in heterogeneous bimetallic catalysts and thereby facilitate the upgrading of the current bimetallic catalysts. In this review, we will discuss the geometric and electronic structures of three representative types of bimetallic catalysts (bimetallic binuclear sites, bimetallic nanoclusters, and nanoparticles) and then summarize the synthesis methodologies and characterization techniques for different bimetallic entities, with emphasis on the recent progress made in the past decade. The catalytic applications of supported bimetallic binuclear sites, bimetallic nanoclusters, and nanoparticles for a series of important reactions are discussed. Finally, we will discuss the future research directions of catalysis based on supported bimetallic catalysts and, more generally, the prospective developments of heterogeneous catalysis in both fundamental research and practical applications.

This review focuses on the chemical methods used to prepare supported bimetallic heterogeneous catalysts, i.e., bimetallic nanoparticles deposited on a support. The review is limited to the preparation of gold-based bimetallic catalysts and moreover to bimetallic nanoparticles supported on powder inorganic supports, i.e., on the surface or in the porosity, and not on model supports such as single crystals.

Abstract The existence of bimetallic particles (and their reducibility and location on/or in the support) in Ru–Co/NaY and Pt–Co/NaY samples has been studied by in situ X‐ray adsorption spectroscopy (XAS). It is established that in Ru–Co/NaY the monometallic clusters maintain their identity, whereas in Pt–Co/NaY the existence of small bimetallic particles can be established. In both cases the results are supported by other techniques, such as XPS and temperature‐programmed reduction. Copyright © 2002 John Wiley & Sons, Ltd.
