Abstract

L'invention porte sur un composant ayant une surface catalytique (12). Selon l'invention, il est prévu que cette surface (12) présente des parties métalliques (14) et des premières parties de contact constituées de MnO2 (13), les parties métalliques étant, de préférence, constituées d'Ag et/ou de Ni. Il s'est avéré d'une manière surprenante que ces paires de matériaux permettent de réaliser un effet catalytique fortement amélioré par comparaison avec les métaux purs. En particulier lors de l'utilisation du Ni, inoffensif d'un point de vue toxicologique, ces surfaces peuvent être utilisées par exemple aussi pour la purification de l'air ambiant, dans le but d'en abaisser la teneur en ozone. La surface peut être appliquée par exemple par un revêtement (15) du composant, la partie métallique et la partie de MnO2 étant appliquées en deux couches (19, 20).
