Fig. 8 shows the pore size distribution curves calculated by Barrett-Joyner-Halenda (BJH) method. The hierarchical structure of the ZSM-5 samples obtained via RPB premix can be observed. Furthermore, the average pore size of ZSM5-RD is larger than that of ZSM5-RS, and an increase of cumulative pore volume in the diameter range of 4.5−8.0 nm is presented for the former sample. In contrast, ZSM5-SS and ZSM5-SD exhibit fewer mesopores than ZSM5-RS and ZSM5-RD, indicating that the textural properties of ZSM-5 samples are greatly affected by the micromixing intensity in the nucleation process.
