A series of ZSM-5/γ-Al2O3 composite materials were prepared under various pretreatment method; The physicochemical properties of composite materials were investigated by XRD, SEM, FTIR to find out optimal pretreatment method. The results showed that the composite materials performance better structure property when γ- Al2O3 was firstly immersed in TPAOH solution under reflux condensation for a period of time and then immersed into anhydrous alcohol before mixed with ZSM-5 precursor solution. The result of infrared spectrum indicated that the formation of Al-OH bond played a key role in the synthesis of micro-mesoporous ZSM-5/γ-Al2O3 composite materials.
Key words: γ-Al2O3 / pretreatment method / TPAOH / ZSM-5/γ-Al2O3 / micro-mesoporopus
