Precious-Metal-Free Nano Catalysts for Diesel Particulate Filters

Hans Prof. Dr. Ferkel; Mischa Bachmann; Hans-Robert Volpp; Klaus Stöwe; Lars Hensgen

The regeneration of filters loaded with particulate matter represents a major challenge for the safe operation of exhaust gas aftertreatment in diesel vehicles. The efficiency of existing soot particulate filter systems can be optimised by using new catalytic materials, amongst other measures. A consortium comprising the Universities of Heidelberg and Saarbrucken as well as the companies Evonik-Degussa, Eberspacher and Volkswagen is presenting current research results from the “NanoKat” joint project funded by the German Federal Ministry of Economics and Technology (BMWi) in which selective soot oxidation catalysts were developed for filter use.

Edelmetallfreie Nanokatalysatoren für Dieselpartikelfilter

Hans Prof. Dr. Ferkel; Mischa Bachmann; Hans-Robert Volpp; Klaus Stöwe; Lars Hensgen

Die Regeneration rusbeladener Partikelfilter stellt eine grose Herausforderung fur den sicheren Betrieb der Abgasnachbehandlung von Dieselfahrzeugen dar. Die Effizienz bestehender Ruspartikelfilter-Systeme kann unter anderem durch den Einsatz neuer katalytischer Werkstoffe optimiert werden. Ein Konsortium aus den Universitaten Heidelberg und Saarbrucken sowie den Unternehmen Evonik-Degussa, Eberspacher und Volkswagen stellt dazu aktuelle Forschungsergebnisse aus dem BMWi-Verbundvorhaben „NanoKat“ vor, in dem neuartige Rusoxidationskatalysatoren fur den Filtereinsatz entwickelt wurden.
