| 英文摘要 | A series of Cu-Mg-Al hydrotalcite compounds with M (II) : 0111) molar ratio of 3: 1 were prepared by co-precipitation method Corresponding mixed oxides were obtained after calcination 500 degrees C(w(CuO)(%) = 0, 5,10,20, denoted as w-CMAO, w =0, 5,10,20). Pt/Cu-Mg-Al-O catalysts were prepared by impregnation with H2PtCl6 solution XRD results showed that Cu was well dispersed in the catalysts and their precursors. NO, storage performance was investigated using NO, adsorption experiment at constant temperatures and decomposition of stored NO, was also studied by TPD method It was shown that although MgO content was decreased due to Cu addition, the activity of NO oxidation was improved, and NO, storage performance was increased effectively. TPD results further showed that the decomposition temperatureofnitrateformedonthecatalystscanbereducedsharplywhen w = 10%similar to 20% ofCuOwasadded. |
