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.
