Micro/mesoporous composite materials with microporous and mesoporous double pores-size distribution were hydrothermally synthesized by using slurry or filtrate of alkali-treated ZSM-5 zeolite and were characterized by XRD, N2 adsorption, FT-IR, TEM and so on. The XRD and TEM patterns indicate the composite materials possess ordered hexagonal structure. The sample MZ-B using filtrate of alkali-treated ZSM-5 zeolite hardly contains raw ZSM-5 particles. However, sample MZ-A originated from the slurry of alkali-treated ZSM-5 zeolite may contain some ZSM-5 crystallites, owing to the differences in concentration and time of alkaline treatment for ZSM-5 zeolite.
