Hierarchical ZSM-5 zeolites were synthesized with cetyltrimethylammonium bromide (CTAB) containing silicalite-1 (S-1) as seed. The characterization results revealed that the CTAB/SiO₂ ratio of 0.005–0.1 in S-1 created abundant intercrystal mesopores in ZSM-5 zeolites and resulted in less strong and weaker acid sites. The hierarchical ZSM-5 had a comparable catalytic performance in methanol to propylene (MTP) reaction with the zeolite synthesized by adding S-1 and CTAB directly in the precursor form as reported in the literature. However, in the present proposed method, the use of CTAB was greatly reduced. The very low-cost and facile method developed in this work is expected to be feasible for the synthesis of other zeolites.

以含有silicalite-1（S-1）的十六烷基三甲基溴化铵（CTAB）为种子合成了分级ZSM-5沸石。表征结果表明，S-1中CTAB / SiO _2的比例为0.005-0.1，在ZSM-5沸石中形成了丰富的晶间介孔，并导致弱酸性位点变弱。分层ZSM-5在甲醇与丙烯（MTP）反应中具有可比的催化性能，与文献报道的通过直接以前体形式添加S-1和CTAB合成的沸石相比。但是，在目前提出的方法中，大大减少了CTAB的使用。预计这项工作中开发的非常低成本且简便的方法对于合成其他沸石是可行的。
