Summary:

The present paper highlights the results of a development program focussing on Pt-based three-way catalysts. It is demonstrated that as compared to state-of-the-art Pt/Rh technologies the utilization oflead to novel catalyst technologies taking better advantage of the lead to novel catalyst technologies taking better advantage of the PGM properties. This yields substantial improvements regarding both aging stability and activity of the catalytic converters. Furthermore, based on the results of a PGM loading study, preferred PGM loadings and ratios were investigated in more detail. In summary, for different application examples it is documented that the newly developed Pt/Rh double layer catalyst is a technical and commercial alternative to the current Pd-based technologies also for high-demanding applications
