Rational Design of RuO2/0.5CeO2 Heterostructure as an Efficient and Stable Electrocatalyst for Acidic Water Splitting

The large-scale commercialization of low-cost Ru-based catalysts in proton exchange membrane water electrolyzers (PEMWEs) is fundamentally hindered by structural degradation through lattice oxygen oxidation (LOM) pathways during acidic oxygen evolution...
