Case Study

 

Lanthanum-Perovskites as NOx-storage catalysts (NSR)

Within the framework of the case study three different lanthanum-perovskites are analyzed concerning their activity as NO_x-storage/reduction catalysts (NSR) resp. regarding their NO-oxidation capability to NO₂ for DOC (Diesel Oxidation Catalyst). Moreover, as the first case study of the Project House, it should serve for demonstration purposes of workflow and synergies at ACA.

Working steps, partly parallel running and matched to each other, cover different analysis methods, tests at laboratory up to vehicle level as well as the development of descriptor models.
