Boosting propylene selectivity is an important issue in the methanol‐to‐olefin (MTO) production. The present study reports the impact of the synthesis temperature on the propylene selectivity of the ZSM‐5 catalyst. The use of a low crystallization temperature results in zeolites with very small particle size, large number of structural defects and lower acid strength. The set of experimental data reveals that lower acid strength and large external surface are the key factors shifting propylene–ethylene selectivity.
