摘要：

Catalytic behavior of silica-supported transition metals for NO reduction with propene in the presence of oxygen was investigated. while both silica and cobalt oxides did not show any activity for the selective NO reduction, impregnated CoO/SiO2 prepared from cobalt acetate showed good activity although the preparation conditions had significant effect on the activity. It was suggested that highly dispersed surface Co2+ ions on silica are responsible for the catalytic activity.
