摘要
(Figure Presented) 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. © 2006 Wiley-VCH Verlag GmbH & Co.
