Understanding the behaviour of active catalyst sites at the atomic level is crucial for optimizing catalytic performance. Here, the evolution of Pt and Cu dopants in Au25 clusters on CeO2 supports is investigated in the water-gas shift (WGS) reaction, using operando XAFS and DRIFTS. Different behaviour is observed for the Cu and Pt dopants during the pretreatment and reaction. The Cu migrates and builds clusters on the support, whereas the Pt creates single-atom active sites on the surface of the cluster, leading to better performance. Doping with both metals induces strong interactions and pretreatment and reaction conditions lead to the growth of the Au clusters, thereby affecting their catalytic behaviour. This highlights importance of understanding the behaviour of atoms at different stages of catalyst evolution. These insights into the atomic dynamics at the different stages are crucial for the precise optimisation of catalysts, which ultimately enables improved catalytic performance.

Bimetallic gold (Au) catalysts present an exceptional development trend toward enhancing the catalytic efficiency of the Au based catalysts. The aim of this review is to provide an insight into synergic effect of the bimetallic Au catalysts in enhancing the efficiency of various processes. The review covers some important aspects involving the effect of particle size, composition, metal-support interaction, morphology and the interaction between Au atom and the secondary metal on catalytic properties of the bimetallic Au catalysts. Particularly, the effect of the core–shell and faceted bimetallic Au catalysts morphologies are clearly articulated in the introduction. In the next section, various spectroscopic and microscopic characterization techniques, which often form a basis for the discussion of the synergic effect of the catalysts in enhancing the process efficiency are also discussed. Finally, we provide a summary on the progress made in catalytic exploration of bimetallic Au catalysts focusing in oxidation of hydrocarbons, fuel cell processes, oxidative transformation of the biomass derived products and photocatalysis.
