Scientists Peel Away Mystery Behind Gold's Catalytic Prowess

Using the world's most powerful microscopes for chemical analysis, scientists have pinpointed where the conversion of carbon monoxide to carbon dioxide occurs when gold is supported on iron oxide. CO oxidation is critical to firefighters and others who wear protect masks when entering a burning building. Bilayer clusters of atoms less than a nanometer in dimension are found to be responsible for a vital oxidation reaction.
