文摘

VOx/x%TiO2/ZSM5 catalysts were prepared tailoring redox and acid properties. TiO2 is heterogeneously dispersed over H-ZSM5 and VOx on the proximities of TiO2. Acid sites of the zeolite increase NO conversion widening temperature working window. Ti-V interactions lead to dispersed isolated and polymeric VOx species formation. V/46Ti/Z provides highest amount of Ti-V interactions and highest dDiNOx activity.
