4.4.4 SCRCatalyst Materials for Exhaust Gas Detection

Daniela Schönauer-Kamin & R. Moos
The application of SCR-catalyst materials like vanadia-doped tungsten-titania (VWT) and ironexchanged zeolites (Fe-ZSM-5) for analyte detection in exhaust gases is investigated. Three detection modes are covered by this overview: the detection of certain gas concentrations with sensing devices comprising SCR-materials, the measurement of the electrical properties of the catalyst materials itself, and the direct determination of the catalyst status during operation by microwave method (an inoperando method). In this work, an overview on the suitability...
