Ces travaux de thèse ont porté sur l'étude approfondie de catalyseurs à base d'argent et d'or dans la réduction catalytique sélective des NOx par C3H6. Pour le système Ag/Al2O3, nous avons réussi à fournir une explication rationnelle de l'origine de l'existence d'un optimum d'activité pour une teneur en Ag de l'ordre de 2 %pds reporté à plusieurs reprises. La caractérisation par NOx-TPD des catalyseurs Ag/Al2O3 a permis d'attribuer l'origine de cet optimum à la teneur maximale en Ag pour laquelle la dispersion quasi-atomique de l'argent est préservée. Nous avons aussi démontré pour la première fois que l'activité des catalyseurs Ag/Al2O3 dans la réduction des NOx par C3H6 en présence de H2 augmentait lorsque la densité surfacique en Ag dimi...
