在弱酸性介质和氟离子存在下,以二乙氨基乙醇为模板剂,采用水热法合成了磷酸锗铝分子筛GeAPO-5。并对其结构和性能进行了表征。研究确证了Ge对AlPO_4-5分子筛骨架的同晶取代。
In the presence of weak acid medium and fluoride ion, GeAPO-5 was synthesized by hydrothermal method using diethylaminoethanol as template. And its structure and performance were characterized. The study confirms the isomorphous substitution of Ge for the AlPO 4 -5 molecular sieve framework.
