| 摘 要： | 考察了用分散法制备的Ｃｕ－Ｍ／ＺＳＭ－５（Ｍ＝Ｃｅ，Ｌａ，Ａｇ）催化剂对ＮＯ直接分解的催化活性，并且用ＸＲＤ、ＳＥＭ、ＴＰＲ、ＸＰＳ及ＩＣＡＰ等手段对催化剂进行了表征。结果表明添加Ｃｅ有利于增加催化剂的铜离子交换度，添加Ａｇ有可能使ＺＳＭ－５分子筛的骨架结构发生改变，从而对催化剂活性产生影响。

| Abstract: | The catalysts Cu M/ZSM 5(M=Ce,La,Ag) were prepared by the disperse method.The performance of the reaction for NO direct decomposition over the catalysts was investigated.The catalysts were characterized by XRD SEM TPR XPS and ICAP techniques.The results indicated that excess loading of copper ions can be obtained by adding Ce ions into the catalyst.By adding Ag ions the zeolite framwork structure can be changed slightly. |
