Interface engineering breaks both stability and activity limits of RuO2 for sustainable water oxidation

Interface engineering breaks both stability and activity limits of RuO2 for sustainable water oxidation Abstract Designing catalytic materials with enhanced stability and activity is crucial for sustainable electrochemical energy technologies. RuO 2 is the most active material for oxygen evolution reaction (OER) in electrolysers aiming at producing ‘green’ hydrogen, however it encounters critical electrochemical oxidation and dissolution issues during reaction. It remains a grand challenge to a...
