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。

In addition,the mechanism isdiscussed on the prevention of interface diffusion via S-passivation.The FexS-dominateinterface reaction layer,is considered to prevent the reaction of Fe with As further meanwhilestabilizes the interface,therefore inhibits the diffusion from the substrate into Fe overlayer,which is different from the model of Anderson.

并且提出了S钝化阻止界面扩散的内在机制，认为在钝化层基底上形成的界面反应层，阻止了Fe和衬底As的反应并稳定了界面，从而阻止衬底元素向薄膜层的扩散，这与Anderson提出的模型不同。

During the cooling to room temperature,β-phase layer with higher Fe content remained, whereas β-phase layer with lower Fe content transformed into α'-Ti martensite. The β-transformed layer and intermetallic compound layer grew parabolically with time at 1223K and 1273K.

在此基础上得出的TA2/A3复合材的工业生产和应用控制在TA2的α-Ti→β-TI转变温度以下进行，从而避免Fe〓Ti，FeTi的形成，保证界面优良性能的结论可指导TA2/A3复合材的工业生产和应用。
