Abstract: The studies on synthesis and characterization of composite molecular sieves in recent years are reviewed in this paper. Several preparation methods are introduced，including two-step crystallization process，seeding method，ion-exchanging，electric charge matching，treated zeolite as silica source. Composite zeolites are characterized with X-ray diffraction (XRD)，nuclear magnetic resonance (NMR)，infrared spectrometry (IR)，NH3-TPD，N2 absorption/desorption，scanning electron microscopy (SEM) and transmission electronic microscopy (TEM)，differential thermal analyses (DTG).
