Abstract

This study develops a MnCo₂O₄/RuO₂ heterostructure that breaks the activity-stability trade-off in acidic oxygen evolution via electron buffering and interface engineering. This electrocatalyst achieves a low overpotential (180 mV@10 mA cm⁻²) and exceptional stability (100 h@50 mA cm⁻²), and enables efficient acidic water splitting (1.55 V@10 mA cm⁻²).
