A process for preparing a catalyst comprising forming an aqueous dispersion of catalytically active calcined refractory metal oxide and a metal compound of the platinum group, said refractory metal oxide having been combined in the form of an aqueous dispersion with a metal compound of the water soluble platinum group, applying said formed dispersion to the external surfaces of a refractory support chemically inert and substantially catalytically inactive, said support being a solid unitary body having a plurality of non-obstructed orifices therethrough, and calcining the support thus coated to provide the support with a catalytically active refractory metal oxide film containing catalytically effective amounts of a platinum group metal.
