中文摘要	FeAlPO-16 molecular sieve with AST topology has been ionothermally prepared under microwave irradiation in succinic acid-choline chloride eutectic mixture for the first time. The structure and morphology of FeAlPO-16 molecular sieve are characterized in detail by powder X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), diffuse reflectance UV–visible (UV–vis) spectroscopy, thermogravimetry–differential scanning calorimetry analysis (TG-DSC) and scanning electron microscopy (SEM). UV–vis results suggest that iron species may partially enter the framework of FeAlPO-16 molecular sieve. SEM images indicate that large spherical particles observed in the images are agglomerates of FeAlPO-16 molecular sieve nanocrystalline (ca. 100 nm in size). Effects of synthesis conditions, such as P2O5/Al2O3 ratio, pyridine/Al2O3 ratio, reaction temperature and crystallization time, as well as iron and aluminum source on the crystallization of FeAlPO-16 molecular sieve are systematically investigated. Experiments show that FeAlPO-16 molecular sieve can be prepared over a wide molar ratio of Al2O3:xP2O5: yPyridine:0.4Fe2O3:58EU (x = 1.0–3.5, y = 0.8–7.8) using aluminum isopropoxide and ferric ammonium citrate as iron and aluminum source, respectively. The synthesis of FeAlPO-16 molecular sieve is highly sensitive to iron source, but not to aluminum source, crystallization temperature and time.
