Proton-Coupled Electron Transfer Governs Heterogeneous Fenton-like Reactivity: Modulation of Surface O–H Bond Dissociation Free Energy and Proton Activity

transfer rates involving surface hydroxyl groups. This paradigm transcends electron-centric approaches by establishing comprehensive theoretical frameworks for reaction enhancement and by providing transformative proton-transfer-based modulation strategies to overcome inherent activity limitations in practical Fenton-like applications.
