The at.-level understanding of the dynamic evolution of the surface structure of bimetallic nanoparticles under industrially relevant operando conditions provides a key guide for improving their catalytic performance. Here, the authors exploit operando x-ray absorption fine structure spectroscopy to determine the dynamic surface reconstruction of Cu/Au bimetallic alloy where single-atom Cu was embedded on the Au nanoparticle, under electrocatalytic conditions. The authors identify the migration of isolated Cu atoms from the vertex position of the Au nanoparticle to the stable (100) plane of the Au 1st atom layer, when the reduction potential is applied. D. functional theory calculations reveal that the surface atom migration would significantly modulate the Au electronic structure, thus serving as the real active site for the catalytic performance. These findings demonstrate the real structural change under electrochem. conditions and provide guidance for the rational design of high-activity bimetallic nanocatalysts. In the part of experimental materials, we found many familiar compounds, such as Bis(acetylacetone)copper(cas: 13395-16-9Synthetic Route of C10H16CuO4)
Bis(acetylacetone)copper(cas: 13395-16-9) is used as PVC stabilizer, and curing agents for epoxy resins, acrylic adhesives and silicone rubbers. It is also used as solvents, lubricant additives, paint drier, and pesticides.Synthetic Route of C10H16CuO4
