文摘
- •
Mass-selected Ru nanoparticles have been investigated for the oxygen evolution reaction in acid.
- •
The effect of thermal oxidation and oxygen plasma treatment has been studied.
- •
The activity and stability could be tuned using different oxidation treatments.
- •
Thermally oxidized nanoparticles exhibited the highest stability but lowest activity.
- •
Plasma treated nanoparticles showed intermediate performance.
