Abstract: The oxidation of copper is essential for several fields, such as corrosion, catalytic methanol synthesis, and CO electroreduction. However, the understanding of the oxidation of copper under various conditions is not complete. Here, we study the oxidation of the vicinal Cu(911) surface by O with in-situ Surface X-ray Diffraction. It was found that the surface facets to (410), (401), and (100) which are stable in the parameter range of =25-400 C and mbar O . The (410) and (401) facets are present until the surface is further oxidized to Cu O, at mbar and above. These results further the knowledge on the oxidation of copper and its surfaces, which may be of importance for a wide range of applications.
