Abstract
The invention relates to a wire made of platinum group metals for producing grid catalysts comprising platinum and rhodium. The invention is characterized in that the wire is made as a sheathed wire and consists of a core and one or more sheaths arranged one over the other outwards from the core in a radially symmetrical manner, and the rhodium concentration in the outermost sheath is lower than the rhodium concentration in the sheath or core arranged directly under the outermost sheath.
