Going way back earlier chemistry days but i think this was just a decomposition by UV light. 2Ag2O (s) --uv--> 4Ag (s) + O2(g) You should check that out though..

1) "The Silver Oxide is split thermically into pure Silver and Oxygen. Oxidation: 2 O2- -> O2 +4 e- Reduction: 4 Ag+ + 4e- -> 4 Ag 2 Ag2O -> 4 Ag + O2" Source and further information: http://www.science-tube.com/index.php?c=chemie§ion=028 V 28 - disruption of silveroxide - Zersetzung von Silberoxid http://www.youtube.com/watch?v=KSeLFr3aCsE 2) "A slurry of Ag2O is readily attacked by acids: Ag2O + 2 HX → 2 AgX + H2O where HX = HF, HCl, HBr, or HI, HO2CCF3. It will also react with solutions of alkali chlorides to precipitate silver chloride, leaving a solution of the corresponding alkali hydroxide. Like many silver compounds, silver oxide is photosensitive. It also decomposes at temperatures above 280 °C." Source and further information: http://en.wikipedia.org/wiki/Silver_oxide
