Abstract
An open-cell, monolithic catalyst for the purification of diesel-engine exhaust gas with a coating of finely divided inorganic oxides containing vanadium and platinum group metal as active components. The active components of the oxidic coating are added as water-soluble precursors which are then converted by means of tempering, preferably in an atmosphere of hydrogen, into the active component.
