| Abstract: | X-ray photoelectron spectroscopy and electron Auger spectroscopy are used to study the surface layers of polycrystalline silver after exposure to water vapor. It is shown that molecular oxygen, atomic oxygen in the composition of AgO and Ag2O, and silver in the zero-valence state are present in the surface region, and also the presence of associated oxygen forms in Ag0–O x -peroxide, superoxide, and ozonide structures is possible. |
