英文摘要	the core-shell molecular sieves comprised of sapo-34 as core and alpo-18 as shell were hydrothermally synthesized and characterized by x-ray diffraction, scanning electron microscopy (sem), and ultra-high resolution field-emission scanning electron microscopy (fe-sem) techniques. the sem results show that the growth of the shell alpo-18 nanocrystals with different orientations and compactness can be controlled by adjustment of the synthesis conditions such as core pretreatment, liquid to solid ratio, and growth number. the ultra-high resolution fe-sem images confirm that the growth performance of the shell alpo-18 is closely related to the surface microstructure of sapo-34, indicating the mechanism that the microstructure on the external surface of the core directs the growth of the shell.
