Herein, a simple and green quasi‐solid‐phase (QSP) method for facile synthesis of proton‐type ZSM‐5 avoiding use of excessive water, dry gel, Na + cation and fluoride is reported. Crystallization by using the stoichiometric amount of TPAOH (tetrapropylammonium hydroxide) at 180 °C for only 12 h gave well‐structured HZSM‐5 crystals with high specific surface area of 429 m 2 g −1 and high thermal stability. 5MRs was observed to closely relate the formation of MFI structure and QSP method exhibits shorter induction period ( t 0 ), higher nucleation rate ( V n ), and faster growth rate ( V g ). Moreover, HZ‐12–180 showed extremely better and rather stable catalytic activity for methanol‐to‐propylene reaction by comparison with commercial HZSM‐5.
