Abstract
The catalyst–electrolyte interface plays a crucial role in proton exchange membrane water electrolysis (PEMWE). However, optimizing the interfacial hydrogen bonding to enhance both catalytic activity and stability remains a significant challenge. Here, a novel catalyst design strategy is proposed based on the hard–soft acid–base principle, employing hard Lewis acids (LAs = ZrO2, TiO2, HfO2) to mediate the reconfiguration of interfacial hydrogen bonding, thereby enhancing the acidic oxygen evolution reaction (OER) performance of RuO2. Mechanistic analysis indicates that LAs prompt a directional evolution from a rigid hydrogen bonding network to free water, enhancing the trapping of interfacial water on the RuO2…
