Краткое описание

The support ZrTiO 4 and the lean-burn NOx trap (LNT) catalyst K/LaCoO 3 /ZrTiO 4 were prepared by co-precipitation and successive impregnation, respectively. This catalyst exhibits much better NOx storage performance than the conventional Pt-containing catalyst K/Pt/ZrTiO 4 . Compared with Pt, the perovskite LaCoO 3 possesses higher capability for NO to NO 2 oxidation, giving a higher NOx storage capacity. NOx is mainly stored as nitrate at 350 °C over K/LaCoO 3 /ZrTiO 4 . Mild sulfation shows little effect on the structure and performance of this catalyst. Total substitution of Pt by perovskite LaCoO 3 to lower the cost of LNT catalysts is feasible.
