Intermetallic junction contribution to the CO electrooxidation on a Pt/Au electrode: the excess voltammetric current
(Springer, 2016-04)
The contribution of the intermetallic junction to the electrocatalytic activity of a Pt/Au electrode for the carbon monoxide oxidation reaction (COOR) in alkaline solution is evaluated on the basis of the excess voltammetric ...
Surface diffusion of poisoning species during CO and formic acid oxidation on PtAu surface. The key role of the active site
(Elsevier Science, 2021-01-31)
A comparative study of the Pt and Pt/Au surface towards CO and formic acid oxidation was performed by conventional electrochemical techniques used in combination with an electrochemical flow cell (four-electrode configuration) ...
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: ...

Catalytic enhancement of formic acid electro-oxidation through surface modifications with gold on supported Pt nanoparticles
(Pergamon-Elsevier Science Ltd, 2019-01)
The Formic Acid Electro-oxidation (FAEO) on Pt/Au Nanoparticles (PtAu NP) supported on Hierarchical Porous Carbon (HPC), was studied by cyclic voltammetry and chronoamperometry. The supported HPC-Pt nanoparticles were ...
Evolution of adsorbed CO on Pt and Pt/Au surface
(Pergamon-Elsevier Science Ltd, 2018-04-20)
In this work, we studied in detail one of the possible limiting-steps during CO oxidation at Pt and Pt/Au electrodes, namely CO adsorption and diffusion at the electrode's surface. With this aim, we used an electroless ...
