Abstract The catalytic activity of Ba2Ru0.67Bi1.33O6, Ba2RuBiO6, Ba3Ru2BiO9 and BaRuO3 towards NO-decomposition prior to and after treatment with NH3 has been studied. About 100% degree of conversion has been achieved at 400°C for samples with the highest percentage of hexagonal stacking in their crystal structures. It has been shown that the active sites are units of two or three face-sharing [RuO6] octahedra in which a strong Ru−Ru interaction takes placevia the common faces.
