Abstract

Domestic appliances are provided with a catalytic deodorizing coating, prepared by applying a coating material containing a polycondensate of at least one hydrolysable organosilane, optionally one or more compounds of glass-forming elements, and particles of one or more catalytically active transition metal oxides, and then heat-treating the applied coating material.
