Cu-SSZ-13 has been successfully commercialized in the aftertreatment system for reducing emitted NOx by the selective catalytic reduction with NH3 (NH3-SCR). However, as global regulations on NOx emission are getting more stringent, the development of catalysts with higher NOx abatement ability is becoming more important. Here, we investigate the effect of Co2+ co-cation on the SCR reactivity of Cu-SSZ-13. Based on the characterization methods. we revealed that introducing Co2+ co-cation change the location of Cu ion species in the Cu-SSZ-13 catalysts. It leads to change in the properties of Cu ion, and as a result, the cobalt introduced Cu-SSZ-13 catalysts demonstrated a higher SCR reactivity than conventional Cu-SSZ-13 catalyst. |
