Ask the Silver Institute: How is Silver Used as a Catalyst?

摘要

A catalyst is a substance that facilitates a chemical process without undergoing change itself. In fact, without catalysts many chemical reactions would proceed so slowly that for all practical purposes, they wouldn't occur at all. Finely-divided silver when heated with oxygenforms silver oxide. Silver oxidebreaks apart into the elements at the ethylene oxide formation temperature of 200 degrees C.
