Abstract

The catalytic performance of Ba-doped Ir/WO₃-SiO₂ for the selective reduction of NO with CO in an oxidizing atmosphere was investigated. The NO reduction activity and durability of the Ir/WO ₃-SiO₂ catalyst were drastically improved by the addition of Ba. Ba played an important role to stabilize the catalytically active Ir-WO_x (x < 3) sites of Ir/WO₃-SiO₂ during the reaction.
