Abstract

In order to improve the catalytic performance of supported-Ir catalysts for the selective reduction of NO with CO, the effect of H₂ was investigated. While adding H₂ showed no or negative effect on NO conversion on Ir/SiO₂, Ba/Ir/SiO₂ and Ir/WO ₃/SiO₂ catalysts, the activity of Ba-doped Ir/WO ₃/SiO₂ catalyst for NO reduction was significantly increased by H₂ addition. The role of H₂ was found to stabilize the catalytically active Ir-WO _x sites during the reaction.
