A process for producing a catalyst body includes spraying an aluminum hydroxide and a metallic aluminum simultaneously but separately onto a support body. In the process, the aluminum hydroxide is thermally converted into an aluminum oxide. In addition, an aluminum/silicon compound is thermally sprayed onto the support body at the same time as but separately from the metallic aluminum, and a metallic active component is supplied. Such a catalyst body produced is suitable, in particular, for breaking down pollutants in a temperature range that lies above 400° C. A catalyst body includes the support body and an active compound thermally sprayed thereon. The active compound includes metallic aluminum, an aluminum oxide, an aluminum/silicon compound, and a metallic active component. The active compound is produced by the separate and simultaneous thermal spraying of the metallic aluminum and the aluminum/silicon compound.
