15 صفحه اولEffect of annealing in oxygen on alloy structures of Pd-Au bimetallic model catalysts.
It has been reported that Pd-Au bimetallic catalysts display improved catalytic performance after adequate calcination. In this study, a model catalyst study was conducted to investigate the effects of annealing in oxygen on the surface structures of Pd-Au alloys by comparing the physicochemical properties of Pd/Au(111) surfaces that were annealed in ultrahigh vacuum (UHV) versus in an oxygen a...
متن کاملAtomic structure of Au-Pd bimetallic alloyed nanoparticles.
Using a two-step seed-mediated growth method, we synthesized bimetallic nanoparticles (NPs) having a gold octahedron core and a palladium epitaxial shell with controlled Pd-shell thickness. The mismatch-release mechanism between the Au core and Pd shell of the NPs was systematically investigated by high-resolution transmission electron microscopy. In the NPs coated with a single atomic layer of...

متن کاملOxygen Activation and Reaction on Pd−Au Bimetallic Surfaces
Pd−Au bimetallic catalysts have shown promising performance for a number of oxidative reactions. The present study utilizes reactive molecular beam scattering (RMBS), reflection−absorption infrared spectroscopy (RAIRS), temperatureprogrammed desorption (TPD), and density functional theory (DFT) techniques in an attempt to enhance the fundamental understanding of oxygen activation and reaction w...
