Journal ArticleDOI
Lattice-strain control of the activity in dealloyed core–shell fuel cell catalysts
Peter Strasser,Peter Strasser,Shirlaine Koh,Toyli Anniyev,Jeffrey Greeley,Karren L. More,Chengfei Yu,Zengcai Liu,Sarp Kaya,Dennis Nordlund,Hirohito Ogasawara,Michael F. Toney,Anders Nilsson +12 more
TL;DR: It is shown how lattice strain can be used experimentally to tune the catalytic activity of dealloyed bimetallic nanoparticles for the oxygen-reduction reaction, a key barrier to the application of fuel cells and metal-air batteries.
Journal ArticleDOI
Real-Time Observation of Surface Bond Breaking with an X-ray Laser
Martina Dell'Angela,Toyli Anniyev,Martin Beye,Martin Beye,Ryan Coffee,Alexander Föhlisch,Alexander Föhlisch,Jörgen Gladh,Tetsuo Katayama,Sarp Kaya,Oleg Krupin,Jerry LaRue,Andreas Møgelhøj,Andreas Møgelhøj,Dennis Nordlund,Jens K. Nørskov,Jens K. Nørskov,Henrik Öberg,Hirohito Ogasawara,Henrik Öström,Lars G. M. Pettersson,William F. Schlotter,Jonas A. Sellberg,Jonas A. Sellberg,F. Sorgenfrei,Joshua J. Turner,Martin Wolf,Wilfried Wurth,Anders Nilsson +28 more
TL;DR: Two distinct adsorption wells—chemisorbed and precursor state separated by an entropy barrier—explain the anomalously high prefactors often observed in desorption of molecules from metals.
Journal ArticleDOI
Oxidation of Pt(111) under Near-Ambient Conditions
Daniel Miller,Henrik Öberg,Sarp Kaya,H. Sanchez Casalongue,Daniel Friebel,Toyli Anniyev,Hirohito Ogasawara,Hendrik Bluhm,Lars G. M. Pettersson,Anders Nilsson,Anders Nilsson +10 more
TL;DR: Pt(111) oxidation at near-ambient O2 pressures has been followed in situ using x-ray photoelectron spectroscopy and ex situ using XAS to reveal significant temperature- and pressure-dependent changes of the Pt-O interaction.
Journal ArticleDOI
Balance of Nanostructure and Bimetallic Interactions in Pt Model Fuel Cell Catalysts: In Situ XAS and DFT Study
Daniel Friebel,Venkatasubramanian Viswanathan,Daniel Miller,Toyli Anniyev,Hirohito Ogasawara,Ask Hjorth Larsen,Christopher P. O'Grady,Jens K. Nørskov,Anders Nilsson +8 more
TL;DR: Using density functional theory, O adsorption energies and corresponding local ORR activities for fcc 3-fold hollow sites with various local geometries that are present in the three-dimensional Pt islands are calculated.
Journal ArticleDOI
In situ X-ray probing reveals fingerprints of surface platinum oxide
Daniel Friebel,Daniel Miller,Christopher P. O'Grady,Toyli Anniyev,John R. Bargar,Uwe Bergmann,Hirohito Ogasawara,Kjartan Thor Wikfeldt,Lars G. M. Pettersson,Anders Nilsson +9 more
TL;DR: Results indicate that the commonly observed large increase of the white-line at high electrochemical potentials on PEMFC cathodes originates from platinum oxide formation, whereas previously proposed chemisorbed oxygen-containing species merely give rise to subtle spectral changes.
