| 摘 要： | 利用水热法合成了 Ｓｉ、Ｚｒ取代型的ＡＰＯ－１１分子筛，井利用ＸＲＤ、ＳＥＭ、ＤＧ－ＤＴＡ等多种手段表征了其晶体结构、表面形貌、孔分布等特性。研究结果显示，ＡＰＯ－ｌｌ、ＳＡＰＯ－１１与ＺＡＰＯ－１１具有相同的晶体结构，不同的表面形貌－ＡＰＯ－１１与ＳＡＰＯ－１１为球形颗粒，而ＺＡＰＯ－１１为棒状晶体，推测这可能与ｐＨ对晶体生长的导向作用有关；三种分子筛除了具有为０．４５ ｎｍ的特征微孔孔径外，还形成了３．８ ｎｍ～３．９ ｎｍ的中孔；ＥＤＸ与孔分布结果显示，Ｚｒ主要以氧化物的形式沉积在分子筛的孔道内，而Ｓｉ部分进入了 ＡＰＯ－１１分子筛的骨架；三种分子筛的热稳定性良好，分解温度超过１０００℃。

| Abstract: | The APO-11 zeolites substituted by Si and Zr (denoted as SAPO-11 and ZAPO-11, respectively) were hydrothermally synthesized. The crystalline structure, surface morphology, and pore distribution were studied by means of XRD, SEM, TG-DTA, EDX and adsorption of nitrogen. The results show that the APO-11, SAPO-11 and ZAPO-11 zeolites have the same crystalline structure and that APO-11 and SAPO-11 are sphere grains While ZAPO-11 is bar crystalline, Which is attributed to the pH value of medium for the growing of crystalline. |
