Cyanide leaching of gold catalysts
Catalysis Communications, 2015 Abstract Gold catalysts remain of great interest, but a high gold price presents a concern. Gold can be leached from gold–titania catalysts using alkaline cyanide solutions. The specific activity of gold for CO oxidation can thereby be increased substantially, though the precise nature of the gold before and after treatment remains unclear.
