High Catalytic Activity and Stability of Hexaaluminate Catalysts for N2O Decomposition

摘要：

　　In this paper, hexaaluminate oxides LaMAl12O19-σ were prepared by using M=Cu ,Ce and Zn as active components to substitute A1l in the hexaaluminate lattice by co-precipitation method.The structure and properties of LaMA11 iO19-σ catalyst was characterized with XRD and BET.The results showed LaCuAl11O19-σ exhibited significant high catalytic activity for the decomposition reaction of N2O.Under the simulated in situ condition, LaCuAl11O19-σ also indicated significant catalytic activity and stability, with N2O conversion of 90% at 635℃.
