摘要: 以二异丙胺或二正丙胺为模板剂用水热合成法合成SAPO-11分子筛,发现pH值及模板剂的种类对所生成的SAPO-11晶体形貌有着明显的影响,通常观察到的球形晶貌实属长形柱体的聚集体。

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.
