By combining the particulate filter and SCR unit of the automotive aftertreatment system, the overall size and cost of the system can be reduced. This work utilizes a simple kinetic model to extract kinetic parameters for soot oxidation by V₂O₅/WO₃-TiO₂ materials, which are known to have a significant SCR activity.
