Content SummaryWe have developed a new family of doubly promoted catalysts based on Pd, which were found to be significantly active and selective for lean NOx reduction by CO+H2. In particular we found that Pd supported on TiO2-modified Al2O3 support is more active and selective than the Pd/Al2O3 catalysts, indicating a pronounced synergy between TiO2 and Al2O3. This support-mediated promotion was found to be further enhanced when these catalysts were additionally modified by an electropositive surface promoter, such as potassium. The resulted benefits with the optimal doubly promoted catalyst were very high de-NOx efficiency (~85% NOx conversion) accompanied with very good N2-selectivities (~85%), i.e., 15-30 additional percentage units in comparison to the selectivity of the original Pd/Al2O3 catalysten
