Silver and hydrogen peroxide

I was watching the Science Channel last night. They were talking about alternative fuel and other "green" stuff. A point was brought out about being careful with H2O2 coming in contact with silver. They indicated that such reaction would be a superheating of the silver. I've never experimented with such. I wonder if that is a precaution with colloidal silver. I assume it would be very minor if so. Colloidal silver is rather minute in silver quantity. Just curious.
