Catalysts useful for oxidizing carbon monoxide and other volatile carbon compounds and for reducing nitrogen oxides are prepared by heating reactive alumina impregnated with ions of a platinum metal, a lanthanide metal, and at least one alkali or alkaline earth metal in amounts which promote substantially complete incorporation of the platinum metal into an aluminum-containing complex metal oxide of the empirical formula ABO.sub.3.
