Although considerable efforts have been devoted to breaking the scaling relationship of adsorbate evolution mechanism (AEM) pathway through modulating the electronic structure of catalysts and the binding energies of reaction intermediate species, limited attention has been paid to the role of interfacial water structure at the interface between catalyst and electrolyte. Here, we anchored RuO2 onto oxophilic MoO3 nanosheet, and realized an optimized connectivity of hydrogen-bond network in the electric double layer (EDL). Through advanced in-situ spectroscopies, we demonstrate that the reconstructed interfacial water molecules can accelerate the dissociation and the follow-up proton transport across the interface, promoting a high-proton-flux interface that ensures simultaneous enhancement of both activity and stability. Consequently, the obtained RuO2/MoO3 heterojunction exhibits remarkable activity and stability in acidic OER (with an overpotential of 235 mV at a current density of 100 mA cm−2 and excellent long-term durability of 420 h at 10 mA cm−2).
