Researchers developed a method to stabilize ruthenium oxide catalysts for acidic water oxidation by introducing tensile strain through interface engineering. The strained ruthenium oxide demonstrated significantly enhanced catalytic performance and durability compared to conventional ruthenium oxide catalysts in proton exchange membrane water electrolyzers. The tensile strain modifies the electronic structure of ruthenium oxide, preventing dissolution and degradation that typically occurs under harsh acidic conditions.


This advancement addresses a critical bottleneck in green hydrogen production through water electrolysis, where catalyst stability in acidic environments has been a major limitation. The improved durability of ruthenium oxide catalysts could enable more efficient and cost-effective hydrogen generation for clean energy applications.
