The overall goal is to develop new methodology for conducting fundamental kinetic models that considers the effect of different activity of different sites, depending on the local structure around the sites and also how this affect the mechanism for metal migration. The methodology is generic and can be applied on many areas and will in this program be applied on emission cleaning. More specifically, we will study in detail the effect of electronic promoters on the activity and stability of metal nano-particles. A second objective is to develop new catalysts that have increased activity and stability using these promoters. The methods that are planned are synthesis, flow reactors with FTIR, XRD, BET, ICP-AES, TPR/TPO/TPD, chemisorption, XPS, isotopic gases, calorimetry, DRIFT, SEM-EDX, HRTEM (research visit to Prof. Wal, Penn State University) and XAS/IR (research visit to Prof. Kröcher, PSI). The results from these experiments will be a base for the kinetic modeling development. The significance of this program is new fundamental methodology for kinetic modeling that can describe the interactions between metal nano-particles and the support/promoter. Another outcome from this program is to develop new catalytic materials using electronic promoters, in order to enhance the low temperature activity and thermal stability. Thus, this program is unique both in the application, as well as new methodology will be developed by combining inter-disciplinary experiments with modeling.
