ABSTRACT:
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, a rare earth metal oxide, and a metallic oxide wherein the metal is IVB, selected VIB metals, and mixtures thereof. The slips or carrier compositions are calcined at a temperature of at least 850.degree. C. before deposition of platinum group metal and characterized by having a surface area of at least 20 m.sup.2 /g after calcination at a temperature of 1200.degree. C. for two hours.
