Surface distortion as a unifying concept and descriptor in oxygen reduction reaction electrocatalysis
Raphaël Chattot,Olivier Le Bacq,Vera Beermann,Stefanie Kühl,Juan Herranz,Sebastian Henning,Laura Kühn,Tristan Asset,Laure Guétaz,Gilles Renou,Jakub Drnec,Pierre Bordet,Alain Pasturel,Alexander Eychmüller,Thomas J. Schmidt,Thomas J. Schmidt,Peter Strasser,Laetitia Dubau,Frédéric Maillard +18 more
TL;DR: It is shown that surface distortion is pivotal to rationalize the electrocatalytic properties of state-of-the-art of PtNi/C nanocatalysts with distinct atomic composition, size, shape and degree of surface defectiveness under a simulated PEMFC cathode environment.
Unsupported Pt-Ni Aerogels with Enhanced High Current Performance and Durability in Fuel Cell Cathodes
Sebastian Henning,Hiroshi Ishikawa,Laura Kühn,Juan Herranz,Elisabeth Müller,Alexander Eychmüller,Thomas J. Schmidt,Thomas J. Schmidt +7 more
TL;DR: In this work, an unsupported Pt-Ni alloy nanochain ensemble (aerogel) demonstrates high current PEFC performance commensurate with that of a carbon-supported benchmark (Pt/C) following optimization of the aerogel's catalyst layer (CL) structure.

Sebastian Henning,Juan Herranz,Hiroshi Ishikawa,Bae-Jung Kim,Daniel F. Abbott,Laura Kühn,Alexander Eychmüller,Thomas J. Schmidt,Thomas J. Schmidt +8 more
TL;DR: In this article, a novel class of unsupported bimetallic alloy catalysts (aerogels) were used as the cathode material in PEFCs under two accelerated stress test conditions and compared it to a state-of-the-art carbon-supported benchmark (Pt/C).
