Ag2O XPS Spectra

XPS data have been obtained from a pressed Ag2O powder obtained from AESAR. The Ag2O sample was annealed in vacuum at 300°C for 30 min. This resulted in a surface primarily composed of Ag2O with a small amount of Ag metal present also. The anneal temperature is above that which results in the decomposition of AgO to Ag2O and below the temperature which results in complete reduction. These spectra will be helpful in XPS studies of O/Ag systems such as alumina-supported silver epoxidation catalysts.
