Abstract

No support: Unsupported nanoporous gold foams with a spongelike morphology (see images) are formed through the selective leaching of silver from a gold–silver alloy. These gold foams are highly active catalysts for CO oxidation at ambient pressures and temperatures down to −20 °C, and have potential applications as membrane catalysts.
