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
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.
Journal ArticleDOI
The impact of geometric and surface electronic properties of pt-catalysts on the particle size effect in electrocatalysis.
Karl Johann Jakob Mayrhofer,Berislav Blizanac,Matthias Arenz,Vojislav R. Stamenkovic,Philip N. Ross,Nenad M. Markovic +5 more
TL;DR: The electronically induced potential shift in the OH adsorption is demonstrated at the CO bulk oxidation, in which adsorbed OH is an educt species and promotes the reaction, and the ORR, where it can act as a surface site blocking species and inhibits the reaction.
Journal ArticleDOI
The effect of the particle size on the kinetics of CO electrooxidation on high surface area Pt catalysts
Matthias Arenz,Matthias Arenz,Karl Johann Jakob Mayrhofer,Vojislav R. Stamenkovic,Berislav Blizanac,Tada Tomoyuki,Philip N. Ross,Nenad M. Markovic +7 more
TL;DR: It is suggested that the catalytic activity for CO adlayer oxidation is predominantly influenced by the ability of the surface to dissociate water and to form OH(ad) on defect sites rather than by CO energetics.

TL;DR: An upper limit of 1.1 eV (90% confidence level) is derived on the absolute mass scale of neutrinos on the Karlsruhe Tritium Neutrino experiment KATRIN, which improves upon previous mass limits from kinematic measurements by almost a factor of 2 and provides model-independent input to cosmological studies of structure formation.
