水热法合成了磷酸锡铝分子筛,并用X荧光分析其组成,X射线粉末衍射测定其晶胞参数。通过电子探针、穆斯堡尔谱、X射线光电子能谱及红外光谱等进行了结构分析。同时,研究了物化及催化性能。结果表明,读分子筛属于AlPO_(4-)5型分子筛的结构类型,Sn~(4+)位于分子筛骨架中。 Hydrothermal synthesis of tin phosphate molecular sieve, and X-ray fluorescence analysis of its composition, X-ray powder diffraction determination of its unit cell parameters. Structural analysis was carried out by electron probe, Mossbauer spectroscopy, X-ray photoelectron spectroscopy and infrared spectroscopy. At the same time, the physicochemical and catalytic properties have been studied. The results show that the molecular sieve belongs to the structural type of AlPO_ (4-) 5 zeolite, Sn 4+ is located in the molecular sieve framework.
