Abstract: A three-way catalyst is described for the purification of automobile exhaust gases formed of an active substance of platinum and rhodium and possibly base metal(s) at a certain weight ratio between the two noble metals and at a certain atomic ratio between the noble and the base metal, which are precipitated onto active aluminum oxide containing certain quantities of CeO2, ZrO2 and Fe2O3, and whereby the catalyst is obtained by impregnating active aluminum oxide, possibly stabilized with alkaline earth metal, with a solution of cerium, zirconium and iron salt which is thereupon calcined in air at 500 DEG -700 DEG C. and then treated after application of an impregnation of salts of the active substance components in a gas current containing hydrogen at temperatures below 650 DEG C.

Abstract: The invention relates to a coating dispersion for producing catalyst-promoting coats on an inert, structure-reinforcing body. The solids of the dispersion are present in various grain size fractions and lead to a rougher coating surface having improved exchange between exhaust gas and catalyst surface and improved heating-up behaviour resulting therefrom.
