Hi Adam Hydrogen peroxide is unstable. It tries to turn to water. To do this It must give up one O per molecule, but as nascent (bare O) is very active, this requires help (to get TWO peroxide molecules cooperation on one project! - one O2 molecule. ANY finely divided powder (or bubbles) assists no end - acting as a focus - a venue for the event! Silver also has lotsa complex oxidation states (unfilled inner electron-shells in its atom). Catalytic silver is specially prepared to have MAXIMUM surface area per gram - maximum venues for the O2 generation process to be located and organised. A great fizzing takes place! Any heat generated (colliding molecules) helps greatly as it decomposes more peroxide. John
