A first aspect of the presente invention pertains to a unique palladium/gold catalyst or pre-catalyst (optionally calcined) that includes rhodium or another metal. A
second aspect pertains to a palladium/gold catalyst or precatalyst at is based on a layered support material where one layer of the support materiel is substantially free of catalytic components. A third aspect pertains to a palladium/gold catalyst or precatalysts on a zirconia containing support material. A fourth aspect pertains to a palladium gold catalyst or pre-catalyst that is produced from substantially chloride free catalytic components.
