Summary

• What is new: A new bridge-adsorbed oxygen mechanism in weak-binding single-atom catalysts for oxygen reduction reactions, challenging established theories.
• Why this is important: Contradiction between the observed considerable ORR activity from weak-binding M-N-C catalysts and theoretical predictions based on the Sabatier principle.
• What the research proposes: A new bridge-adsorbed oxygen mechanism identified using a pH-field coupled microkinetic model and experiments, alongside a unified scaling relation model incorporating kinetics.
• Results: The new model shows improved alignment with experimental data and offers a design principle for high-performance SACs by leveraging weak-binding atoms.
