Dissolution of Noble Metals during Oxygen Evolution in Acidic Media
Max Planck Society · Max-Planck-Institut für Nachhaltige Materialien
Abstract
Abstract The electrochemical production of hydrogen and hydrocarbons is considered to play a decisive role in the conversion and storage of excess amounts of renewable energy. The electrocatalysis of the oxygen evolution reaction (OER), however, faces significant challenges for practical implementation of electrolyzers. In this work, a comparative study on the activity and stability of oxidized polycrystalline noble metals during the OER is presented. All studied metals exhibit transient and steady‐state dissolution. Transient dissolution takes place during oxide formation and reduction. Steady‐state dissolution depends on the OER mechanism on each surface: On metals such as Ru and Au, for which oxygen from…
