By subjecting the electrochemical cell or the electrolyte to ultrasonication while conducting a typical RDE-based measurement of the OER performance of a polycrystalline iridium-disk electrode, we demonstrate that it is the accumulation of microscopic oxygen bubbles that is responsible for the rapid OER catalyst performance decay observed during RDE experiments.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1021\/acsaem.0c01944 Authors: Alexandra Hartig\u2010Wei\u00df, Mohammad Fathi Tovini, Hubert A.
