Abstract

The invention relates to a oxidation catalyst (1) having a supporting material (2) with TiO2, preferably also with WO3, on which a catalytically active component (4) is applied. The substrate (2) can also comprise a base material (6) made of cordierite on which an active layer (11) is applied, said layer consisting of a mixture of TiO2 and a noble metal, preferably platinum.
