Abstract

A process for producing a catalyst with a catalytically active composition on a support body by thermal spraying and a catalyst produced thereby. A spraying material including a reactive precursor of at least one component of the catalytically active composition is thermally sprayed onto the support body and the reactive precursor is converted to form the component. A catalyst having a high BET surface area can be produced in this way. At the same time, an inactivation of a thermally sensitive component during the spraying process can be avoided.
