This new electrocatalyst improves corrosion resistance and performance in proton exchange membrane water electrolysis, suggesting efficient hydrogen production.
Key Points
The Ir 1 Ru/TiO 2 catalyst achieved a high initial mass activity of 1971.5 A, enhancing hydrogen production efficiency.
Stable operation was demonstrated at 10 mA cm −2 for over 3200 h and at 2 A cm −2 for 2000 h, showing long-lasting performance.
The embedded structure effectively reduces the dissolution and oxidation of active sites, significantly improving the catalyst's lifespan.
The hierarchical atomic assembly strategy used in synthesis provides a novel approach for developing advanced electrocatalysts.
