Fe-SAPO-34 silicoaluminophosphates having Fe2+ organic complexes and methods for their direct synthesis in the absence of a co-templating agent are described. Fe-SAPO-34 silicoaluminophosphate having Fe3+ located in extra-framework locations within the pores of cages of the crystal are described. They are prepared by calcining the Fe-SAPO-34 silicoaluminphosphates containing Fe2+ polyamine complexes. Methods of using the Fe-SAPO- 34 having Fe3+ located in extra-framework locations within the pores of cages of the crystal in the treatment of exhaust gases are described. 描述了具有Fe有机络合物的Fe-SAPO-34硅铝磷酸盐和在不存在共模板剂下，它们的直接合成方法。描述了Fe-SAPO-34硅铝磷酸盐，其具有位于晶体笼的孔内骨架外位置中的Fe。通过煅烧含有Fe多胺络合物的Fe-SAPO-34硅铝磷酸盐来制备它们。描述了在废气处理中使用具有位于晶体笼的孔内骨架外位置中的Fe的Fe-SAPO-34的方法。
