Abstract

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.
