- •
MEIS shows that CO adsorption on a cobalt-rich bimetallic surface induces Co enrichment presumably due to the unfavourable adsorption energy of CO on isolated Pd atoms.
- •
RAIRS shows that CO adsorption on a p(2x1)-CoPd alloy on Pd{111} results in a rearrangement of surface Co and Pd atoms.
- •
MEIS shows that CO adsorption on a Pd-rich bimetallic surface leads to Co segregation to the surface layer.
