Binding of Oxygen on Single-Atom Sites on Au/Pd(100) Alloys with High Gold Coverages
(American Chemical Society, 2021-05-03)
Oxygen adsorption was studied on a Au/Pd(100) single crystal as a model for single-atom-alloy catalysts since the surface contains isolated palladium atoms surrounded by gold at high gold coverages, and density functional ...
Combining IR Spectroscopy and Monte Carlo Simulations to Identify CO Adsorption Sites on Bimetallic Alloys
(American Chemical Society, 2019-01)
The atomic distribution on the surface of alloys dictates the nature of the ensembles available as possible active sites during catalytic reactions. In the present work, an infrared spectroscopic study of carbon monoxide ...
Pt catalysts supported on ion exchange resins for selective glycerol oxidation. Effect of Au incorporation
(Elsevier Science, 2017-05)
In this paper, bimetallic Pt-Au catalysts were studied for the selective liquid phase oxidation of glycerol. The support used was a macroporous weak anion exchange resin. Two different preparation methods were employed: ...

Electrochemical formation of ultra-thin Ag/Cd films onto Au(111) substrates
(Elsevier Science Inc, 2007-06)
The formation of an ultrathin bilayer of Ag/Cd in the system Au(111)/Ag+,Cd2+,SO2 2/4 has been studied by conventional electro-chemical techniques and in situ scanning tunneling microscopy (STM). Cyclic voltammetric ...

Bimetallic ag-au nanoparticles inside mesoporous titania thin films: Synthesis by photoreduction and galvanic replacement, and catalytic activity
(Wiley VCH Verlag, 2020-02)
In this work, the synthesis and catalytic activity of bimetallic Ag–Au nanoparticles (NPs) supported in TiO2 mesoporous thin films (MTFs) are presented. The composite materials were obtained through a two-step procedure, ...
