Abstract: A method for producing a catalyst system for gas reactions comprising at least one planar structure of noble metal having gas-permeable openings, comprising the steps of: (1) providing at least one noble metal powder consisting of at least substantially spherical noble metal particles, and (2) repeatedly applying the noble metal powder or powders provided in step (1) in layers to a substrate in a build chamber, respectively followed by an at least partial melting of the respective noble metal powder applied as a layer with high-energy radiation, and allowing the melted noble metal powder to solidify within the scope of additive manufacturing.

Abstract: The present invention relates to a powder composed of spherical noble-metal particles having a particle size distribution with a d10 value of ?10.0 ?m and a d90 value of ?80.0 ?m.

Abstract: A catalyst includes a gas-permeable textile sheet material made of noble-metal-containing wire having a three-dimensional secondary structure produced thereon. The secondary structure is a three-dimensional dent structure including dents arranged adjacent to each other in rows in two spatial directions. The dents are in the form of a hexagon. The dent structure is formed by self-organization in a denting process.
