Interface-Strengthened Ru-Based Electrocatalyst for High-Efficiency Proton Exchange Membrane Water Electrolysis at Industrial-Level Current Density.

ABSTRACT: Developing an OER electrocatalyst that balances high performance with low cost is crucial for widely adopting PEM water electrolyzers. Ru-based catalysts are gaining attention for their cost-effectiveness and high activity, positioning them as promising alternatives to Ir-based catalysts. However, Ru-based catalysts can be prone to oxidation at high potentials, compromising their durability. In this study, we utilize a simple synthesis method to synthesize a SnO₂, Nb₂O₅, and RuO₂ composite catalyst (SnO₂/Nb₂O₅@RuO₂) with multiple interfaces and abundant oxygen vacancies. The large surface area and numerous active sites of the SnO₂/Nb₂O₅@RuO₂ catalyst lead to o
