Pd-containing perovskites display better performance reduction below 200°C producing considerably less N2O than a commercial TWC catalyst composition. This commercial TWC catalyst produced five times more N2O than the Pd-containing perovskites. In addition, the N2O formation rates of the Pd- containing perovskites remained below 50ppm over the tested temperature range.
