Enhanced Oxygen Evolution in RuO2 Thin Films by Exchange-Coupling-Assisted Altermagnetic Domain Ordering.
Efficient water electrolysis is central to renewable energy storage but remains limited by the sluggish oxygen evolution reaction (OER). Among state-of-the-art catalysts, rutile RuO2 delivers exceptional activity yet suffers from instability and poorly explored spin effects. Here, we demonstrate OER enhancement in alte...
