A series of Beta, ZSM-5 and MCM-22 zeolites modified with metal ions (such as Fe 3+ , Co 2+ , Ce 3+ , Ni 2+ and Cu 2+ ) for catalytic decomposition of N2O were prepared by using wet ion exchange method. The effects of different metal ions, the contents of metal ions and silicon aluminum ratio on catalytic decomposition activities of N2O were investigated, respectively. The results indicated that Beta with a SiO2/Al2O3=30 and 1% Fe 3+ have better catalytic decomposition activities to N2O, the completed catalytic decomposition temperature to 35% N2O in the condition of 4000 h-1 GVSH is 350 0 C.
