DEVELOPMENT OF NOVEL CATALYST COMPOSITES VIA THE SYNERGY OF STRUCTURE AND SURFACE PROMOTERS FOR THE SIMULTANEOUS ABATEMENT OF NITROGEN (NOX) AND NITROUS (N2O) OXIDES

Abstract: 

Nitrogen oxides (NOx) abatement is a subject of considerable environmental interest, since NOX significantly contribute to a variety of environmental problems. Recently, considerable efforts have also been devoted to nitrous oxide (N2O) emission control, due to its harmful impact on stratospheric ozone depletion and its outstanding Global Warming Potential (GWP). In this context, it is of major environmental importance, comprising at the same time a challenging issue in the area of environmental catalysis, to achieve the simultaneous abatement of NOX and N2O emissions, which usually coexist in combustion effluent gases. This is exactly the main target of the present research project, which aims at developing highly active and selective catalytic materials, which are able to simultaneously control the NOX and N2O emissions.

To achieve this goal, novel nanostructured catalysts will be synthesized, based on only one noble metal at very low loadings, appropriately stabilized and promoted by both structure (e.g. lanthanides) and surface (e.g. alkalis) modifiers. To this end the physicochemical properties of as prepared composites will be adjusted by combining the appropriate synthesis procedure with the simultaneous use of structure and surface modifiers. To scale up, the optimum promoted catalytic materials will be washcoated on ceramic cordierite monoliths and will be tested under simulated exhaust conditions in a pilot unit.

Finally, from the fundamental research viewpoint, based on advanced structure and surface characterization techniques, the present project aims to gain insight into the mechanism of structure and/or surface promoters-and especially of their synergy- in the area of heterogeneous catalysis. In this context, the knowledge and experience that will be gained, is expected to contribute to a research methodology and scientific approach for addressing various catalytic processes of environmental and/or energy importance.
