- •
We studied incorporation of oxygen into Ru(0001) underneath silicate and aluminosilicate films;
- •
Oxygen in the silicate does not scramble with oxygen in the ambient even at near atmospheric pressures and elevated temperatures;
- •
The results indicate considerable spatial effects for oxidation of metal surfaces in the confined space;
- •
The aluminosilicate films completely suppress the Ru oxidation.
