The catalytic activity for the selective reduction of NO with CO over Ir/SiO2 was greatly increased by the addition of a W species. The active site for reduction of NO over Ir/WO3–SiO2 was an Ir–WO x species (2.92 ≤ x ≤ 3). The role of the Ir–WO x active site was to promote the NO dissociation step.
