Component having a catalytic surface, method for producing same and use of said component

摘要

A component includes a catalyst surface having regions of CeO2 and regions of MnO2 that contact the regions of CeO2. Said material pairings may provide an improved catalytic effect compared to pure oxides. Said surfaces can, for example, also be used in indoor air purification to reduce the ozone content. The surface can, for example, be applied by coating the component and processed by cold-gas spraying of, for example, particles made of MnO2, to which CeO2 is applied.

1. A component part, comprising:
a catalyst surface including:
surface regions of CeO2,surface regions of MnO2 in contact with and surrounding the surface regions of CeO2, to define a plurality of islands of CeO2 physically separated and spaced apart from each other at the catalyst surface by the surface regions of MnO2, and metallic surface regions of Ag or Ni or Co or Cu or Sn or Zn or alloys of at least one of these metals, the metallic surface regions being adjacent and in contact with the surface regions of MnO2.
