Iron-containing aluminophosphate molecular sieve with LEV topology (Fe-LEV molecular sieve) has been successfully synthesized by a microwave-assisted ionothermal method in low-dosage of eutectic mixture solvent, which is the first example of Fe incorporated aluminophosphates with the LEV-zeotype structure. The optimum synthetic conditions of this material were refined. The structure and morphology of a representative Fe-LEV sample, as well as the structure directing effect of eutectic mixture were thoroughly analyzed by various techniques including XRD, ²⁷Al and ³¹P MAS NMR, ICP-AES, DR UV-Vis, ESR, XPS, N₂ adsorption/desorption, NH₃-TPD, SEM, TEM, EDX, CHN elemental analysis, TG-DTA and FT-IR spectra. It was found that the combined effect of the starting precursor and a suitable structure-directing agent yielded an appropriate crystallization system of Fe-LEV molecular sieve, for which choline cations and intact tetraethylammonium bromide molecules were identified to be the structure-directing agents. The calcined Fe-LEV molecular sieve exhibits higher specific surface area and iron content, as well as a medium acidity and special hierarchical structure with both micropores and mesopores, implying that these zeolitic materials have a great potential in some industrially relevant applications.

通过微波辅助电热法在低剂量共晶混合物溶剂中成功合成了具有LEV拓扑结构的含铁铝磷酸盐分子筛（Fe-LEV分子筛），这是Fe掺入的LEV沸石型铝磷酸盐的第一个实例结构体。优化了该材料的最佳合成条件。用XRD，²⁷ Al和³¹ P MAS NMR，ICP-AES，DR UV-Vis，ESR， XPS，N ₂吸附/解吸，NH ₃-TPD，SEM，TEM，EDX，CHN元素分析，TG-DTA和FT-IR光谱。发现起始前体和合适的结构导向剂的共同作用产生了合适的Fe-LEV分子筛的结晶体系，对于该结晶体系，胆碱阳离子和完整的四乙基溴化铵分子被鉴定为结构导向剂。煅烧后的Fe-LEV分子筛具有较高的比表面积和铁含量，并且具有中等酸度和特殊的具有微孔和中孔的分级结构，这意味着这些沸石材料在某些工业相关应用中具有巨大的潜力。
