Nature Chemistry, Published online: 22 April 2026; doi:10.1038/s41557-026-02130-9 The oxygen evolution reaction remains a bottleneck for renewable fuels research. Now, temperature-dependent electrochemistry and operando X-ray characterization demonstrate that both catalyst restructuring and solvent ordering dictate reaction kinetics, offering new insights for engineering electrode–electrolyte interfaces.
