A composite template method was used to synthesize a ZSM-5 molecular sieve containing intracrystalline mesopores. In this paper, the charge ratio and the amount of mesoporous template have been set as variables. The synthesized samples were characterized through XRD, TEM and BET and its absorption performance of toluene has been qualitatively analyzed. The results showed that the synthesis of ZSM-5 structure required a suitable charge ratio and the amount of composite templating agent. The specific surface area of molecular sieve with ZSM-5 structure can be up to 499 m2/g, which charge ratio was 0.8. Besides, the maximum of adsorption amount of static adsorption and adsorption rate of dynamic adsorption were 265 mg/g and 16.75% respectively.
