Platinum forms nano-bubbles

(Deutsches Elektronen-Synchrotron DESY) Platinum, a noble metal, is oxidized more quickly than expected under conditions that are technologically relevant. This has emerged from a study jointly conducted by the DESY NanoLab and the University of Vienna. Devices that contain platinum, such as the catalytic converters used to reduce exhaust emissions in cars, can suffer a loss in efficacy as a result of this reaction. The team around principal author Thomas Keller, from DESY and the University of Hamburg, is presenting its findings in the journal Solid State Ionics.
