Abstract

XPS and TDS methods have been employed to study interaction of oxygen with the surface of polycrystalline silver over wide temperature (420–620 K) ranges. O2 adsorption on Ag at T<470 K leads to a single surface state. The interaction of oxygen with Ag at T>470 K is accompanied by oxygen penetration into the bulk and subsequent formation of subsurface oxygen.

Abstract

Методами РФЭС и ТДС исследовано взаимодействие кислорода с поверхносью поликристаллического серебра в широком диалозоне температур (420–620 К). Обнаружено, что адсорвция кислорода на Ag при Т<470 К приводит только к одному поверхностному состоянию. Взаимодействие кислорода с Ag при Т>470 К приводит к внедрению кислорода в оббем, а затем к образованию поверхностного кислорода.
