  • The deployment of fuel cells demands more efficient electrode–electrolyte interfaces to catalyse the oxygen reduction reaction (ORR). A kinetic ORR descriptor is put forward, which is related to the rate of the *O ↔ *OH transition and includes electrolyte effects via the role of non-specifically adsorbed anions.

  • Platinum dissolution and restructuring due to surface oxidation are primary degradation mechanisms of platinum-based electrocatalysts. Now, stark differences are reported in the mechanism for the oxidative extraction of platinum atoms on (111) and (100) single crystals, providing a detailed explanation for the enhanced dissolution on the latter surface.

  • Although Fe doping boosts the electrocatalytic performance of NiOOH materials for the oxygen evolution reaction, the underlying mechanism has been not well understood. Here, the authors reveal Fe low-spin state configuration as a main driver of this electrochemical phenomenon.
