Effect of the Ru concentration on the CO tolerance and the oxidizability of a composition spread PtRu/Pt(111) near-surface alloy Open
We prepared a Pt-terminated PtRu near-surface alloy with a lateral concentration gradient on Pt(111). This allows us to determine the CO tolerance and oxidizability under identical conditions for different alloy compositions.
