通过常规方法合成微孔ZSM-5并对其进行NaOH处理，KF体系下采用三甲氧基[3-（苯氨基）丙基]硅烷（PHAPTMS）为介孔模板剂分别制备4种具有不同孔道结构的ZSM-5。通过X射线衍射、透射电子显微镜、氩气物理吸附等表征手段证明所合成的4种ZSM-5均具有MFI拓扑结构且结晶良好，而加入PHAPTMS得到的样品的介孔体积最大。利用等体积浸渍硝酸铁溶液的方法将铁引入ZSM-5中，焙烧后得到4种Fe/ZSM-5。实验结果表明，介孔的引入显著地提高了催化剂在亚甲基蓝降解反应中的活性，其活性源于ZSM-5的酸性和铁的相互作用。

Micropore ZSM-5 molecular sieves are synthesized by means of traditional synthesis method,and is treated by NaOH.Four kinds of ZSM-5 samples with different pore structure are synthesized by using trimethoxy[3-(phenylamino)propyl] silane (PHAPTMS) as the mesoporous template in a KF system.Characterizations such as X-ray diffraction (XRD),transmission electron microscopy (TEM) and Argon adsorption-desorption indicate that the synthesized ZSM-5 samples are well crystalized and present typical MFI topology.ZSM-5-PHP sample added with PHAPTMS contains lots of hierarchical pores.Through impregnation of ferric nitrate solution,Fe is induced into ZSM-5 and Fe/ZSM-5 is finally got after calcination.Experimental results indicate mesopores can promote the catalytic activity of the catalyst in catalyzing degradation of methylene,and the activity comes from the combination between Fe and the acid of ZSM-5.
