Zusammenfassung:	Catalysts having good high temperature stability which are particularly useful for selected high temperature reactions are disclosed as are methods for their preparation and use. The catalytically-active materials include platinum group metal deposited on a catalytic slip or composite which contains a mixture of alumina, selected VIB metal oxides, and a metallic oxide or oxide mixture wherein the metal or metals are selected IIA, IVA, and IIA-IVA mixtures, selected IIA and IVB mixtures and selected IVA and IVB mixtures. The slips or carrier compositions are calcined at a temperature of at least 500 DEG C. before deposition of platinum group metal and characterized by having a surface area of at least 20 m2/g after calcination at a temperature of 1200 DEG C. for 2 hours.
