Abstract

A component has a catalyst surface including metal regions and regions of MnO2 contacting the former, wherein the metal regions are made of Co and/or Sn and/or Zn (or alloys of said metals). Said material pairings achieve a significantly improved catalytic effect in comparison to the pure metals. Said surfaces can be used, for example, in room air purification for reducing ozone content. The surface can be applied, for example, by coating the component, wherein the metal region and the region of MnO2 are applied in two layers.
