Combined TPR, hydrogen chemisorption and oxygen uptake measurements were performed on the following catalyst: Pd/g-Al2O3 , VOx/g-Al2O3 and Pd-VOx/g-Al2O3 . It was found that an effective contact between palladium and vanadium exist in the binary system. Catalytic experiments for the NO-CO reaction have shown an increase in N2 selectivity when comparing the binary catalyst with its vanadium free counterpart. VOx entities in close proximity with the noble metal or highly dispersed palladium may be responsible of the enhace of N2 selectivity.
