英文摘要	ATN-type FeAPO-39 molecular sieves with high iron content has been successfully synthesized under non-solvent conditions, which is the first example of iron-incorporated aluminophosphate with the ATN-zeotype structure. The optimum synthetic conditions of this material were refined. It was found that the following synthetic conditions, i.e. a low P2O5/Al2O3 ratio, a high DPA/Al2O3 ratio (DPA: di-n-propylamine) and an elevated crystallization temperature, seemed to be more favorable for the non-solvent synthesis of ATN phase. The composition and structural characteristics of resultant relatively pure FeAPO-39 molecular sieves were intensively studied by XRD, FT-IR, TG-DTA, CHN elemental analysis, ICP-AES, SEM, TEM, N-2 physisorption, UV/Vis diffuse reflectance spectroscopy and Mossbauer spectroscopy analyses. The iron content and zeolite yield of FeAPO-39 material were found to be as high as 5.56 wt.-% and 82.6%, respectively. The results of FT-IR, TG-DTA and CHN elemental analysis indicate that DPA molecules may co-direct the synthesis of ATN zeolites along with additional structure-directing agent NH4+ ions resulting from iron source. Owing to the specific structure-directing role provided by iron source, the synthetic strategy presented here may find a potential application in the non-solvent synthesis of other aluminosilicate and aluminophosphate zeolites with novel frameworks.
