Abstract: Microporous silicoaluminophosphate SAPO-11 was synthesized hydrothermally with di-n-propylamine or di-iso-propylamine as a template. The results show that pH values and types of template directly affected the habit of SAPO-11 crystalline. The scanning electron micrographs of a typical SAPO-11 generally show sphere-like growth aggregates. Actually,it was found that these aggregates substantially were composed of single crystals with lower symmetric hexagonal prisms,approximately 5-7μm across. |
