“…The surface area of silver can be increased and cleaned with oxygen adsorption, outgassing, and reduction methods (OAOR). 26 Kestenbaum et al 23 after applying OAOR for microreactor silver foils prior to ethylene epoxidation found that the treatment only slightly increased the catalytic activity, however, during the first 100 h of operation, additional active sites were formed or the activity of existing sites increased.…”

“…Although most of the-quantitative work reported was at temperatures between 300 and 400° C, cyclic reduction and reoxygenation has been carried out near 100° C on silv.er supported by glass wool[27]. • After extensive outgassing, adsorption, outgassing, and reduction cycling on silver powder, both H 2 and CO" reduced all but 0.1 monolayer of oxygen from the surface at room temperature[28].Results .of reduction reactions on (11 0) single crystals are similar to those obtained with powders[29].The adsorption of sulfur dioxide on silver is even less studied than co 2 and H 2 o adsorp-Sulfur is rer:noved as so 2 and clean silver obtained in the early stages of cyclic oxygen adsorption and carbon monoxide reduction at 350° C[30]. One cycle was sufficient to _o~dize the sulfur to .a gaseo~s species at this temperature, but for solar applications the question of reactivity between sulfur and oxygen remains open.…”

“…Furthermore, at high temperatures (800-900 K), O β can re-diffuse towards the surface without immediate desorption. At these temperatures, the existence of a well-structured binary compound like Ag 2 O oxide is excluded [14] since the temperature is higher than the thermodynamic decomposition temperature of Ag 2 O [15]. This "surface-embedded" oxygen is referred to as O γ .…”
