摘要：
A catalyst for NOx storage/reduction was prepared to improve the activity of Ba–Pt/γ-Al2O3 by replacing Ba with a mixture of Ba and Mg. The catalyst was prepared by impregnating Pt and then co-impregnating Ba and Mg (Mg:Ba molar ratio = 1) on commercial γ-Al2O3. The tests have been carried out in the presence of CO2 at temperatures between 200 and 400 °C in order to understand the role of both the feed and various alkaline-earth metals. The storage capacity of the two catalysts was different like the mechanism in the reduction process.
