Abstract: A catalyst network comprising at least one noble metal wire that contains at least one dispersion-strengthened noble metal alloy. The invention also relates to a catalyst system containing at least one catalyst network according to the invention, and to a method for the catalytic oxidation of ammonia in which a catalyst network according to the invention is used.

Abstract: A method for producing a two-layer noble metal mesh on a flatbed knitting machine which has a first and a second needle bed. The method comprises: providing at least one wire containing noble metal; and knitting the noble metal mesh. The first and second layers of the noble metal mesh are knitted simultaneously on the first and second needle beds, these two parts being at least in part connected at their two abutting edges by connecting stitches.

Abstract: A method for producing a two-layer noble metal mesh on a flatbed knitting machine which has a first and a second needle bed. The method comprises: providing at least one wire containing noble metal; and knitting the noble metal mesh. The first and second layers of the noble metal mesh are knitted simultaneously on the first and second needle bed, and a supporting mesh is knitted on the first and second needle bed using a supporting thread. An abutting edge of the supporting mesh is connected to the two layers of the noble metal mesh via connecting stitches and knitted via both needle beds in the knitting rows containing the connection.
