As to MNa-ZSM-5, the order is CuNa-ZSM-5〓AgNa-ZSM-5＞CeNa-ZSM-5＞ CoNa-ZSM-5〓FeNa-ZSM-5＞Na-ZSM-5. Among the samples tested, CoHZSM-5 shows the highest activity, the conversion of NO is about 60%, and the activity is higher than that of CoNa-ZSM-5 with the same exchanged level. Suggests that the exist of some Bronsted acidity is benefited for this reaction. For Fe-ZSM-5, the activity are changed obviously with the various of preparation condition. It was also found that mordenite zeolite is a good support for this reaction.

其中，Co-HZSM-5表现出最佳的反应活性，NO的最高转化率达60％以上，并且活性明显高于具有相同交换度的CoNa-ZSM-5，表明适量的酸中心存在有利于该反应的进行；对于Fe-ZSM-5，制备条件不同Fe-ZSM-5的反应活性影响很大，反应的活性中心应是处在交换位上的铁离子；另外，通过考察不同载体对铁离子交换分子筛催化剂反应性能的影响，发现丝光分子筛也是较好的催化剂载体。
