Journal ArticleDOI
Trends in electrocatalysis on extended and nanoscale Pt-bimetallic alloy surfaces
Vojislav R. Stamenkovic,Vojislav R. Stamenkovic,Bongjin Simon Mun,Bongjin Simon Mun,Matthias Arenz,Karl Johann Jakob Mayrhofer,Chris Lucas,Guofeng Wang,Philip N. Ross,Nenad M. Markovic +9 more
TL;DR: The electrocatalytic trends established for extended surfaces are used to explain the activity pattern of Pt(3)M nanocatalysts as well as to provide a fundamental basis for the catalytic enhancement of cathode catalysts.
Journal ArticleDOI
Changing the Activity of Electrocatalysts for Oxygen Reduction by Tuning the Surface Electronic Structure
Vojislav R. Stamenkovic,Bongjinsimon Mun,Karl Johann Jakob Mayrhofer,Philip N. Ross,Nenad M. Markovic,Jan Rossmeisl,Jeffrey Greeley,Jens K. Nørskov +7 more
TL;DR: Pt alloys involving 3d metals are better catalysts than Pt because the electronic structure of the Pt atoms in the surface of these alloys has been modified slightly, and it is shown that electrocatalysts can be designed on the basis of fundamental insight.
Journal ArticleDOI
Oxygen electrochemistry as a cornerstone for sustainable energy conversion
TL;DR: A promising strategy to develop such an understanding is the investigation of the impact of material properties on reaction activity/selectivity and on catalyst stability under the conditions of operation, as well as the application of complementary in situ techniques for the Investigation of catalyst structure and composition.
Journal ArticleDOI
Effect of surface composition on electronic structure, stability, and electrocatalytic properties of Pt-transition metal alloys: Pt-skin versus Pt-skeleton surfaces.
Vojislav R. Stamenkovic,Bongjin Simon Mun,Karl Johann Jakob Mayrhofer,Philip N. Ross,Nenad M. Markovic +4 more
TL;DR: These three different near-surface compositions (Pt-skin, Pt-skeleton, and pure polycrystalline Pt) all having pure-Pt outermost layers are found to have different electronic structures, which originates from different arrangements of subsurface atoms of the alloying component.
Journal ArticleDOI
Measurement of oxygen reduction activities via the rotating disc electrode method : from Pt model surfaces to carbon-supported high surface area catalysts.
Karl Johann Jakob Mayrhofer,Dusan Strmcnik,Berislav Blizanac,Vojislav R. Stamenkovic,Matthias Arenz,Nenad M. Markovic +5 more
TL;DR: In this article, the authors scrutinize the thin-film rotating disc electrode (TF-RDE) method for investigating the electrocatalytic activity of high surface area catalysts.
