Abstract (en)
[origin: WO2012059423A1] The invention relates to a catalytic composition comprising a noble metal on an acid tungsten-containing mixed oxide, to a method for producing the catalytic composition, and to the use of the catalytic composition as an oxidation catalyst. The invention further relates to a catalyst molding which comprises the catalytic composition on a substrate, to a wash coat containing the catalytic composition according to the invention, and to the use of the wash coat for producing a coated catalyst molding.
