A crystal structure of a novel aluminophosphate AlPO-NS, which has a crystal morphology of stacked hexagonal plate crystallites (30–50 nm in thickness), was determined utilizing a combination of 3D-ED, powder X-ray diffraction, and solid-state NMR experiments. We previously reported that AlPO-NS could be obtained from a synthetic solution for a typical aluminophosphate AlPO₄-5 (Al₂O₃ : P₂O₃ : triethylamine : H₂O = 1.0 : 1.0 : 3.0 : 250) via AlPO₄-5 by prolonged hydrothermal reaction time (T. Kodaira et al. Microporous and Mesoporous Materials 162, 32–35 (2012).). The 3D-ED/microED analysis successfully revealed that AlPO-NS consists of two layers in a unit cell of a hexagonal system. A space group and lattice constants were P6₃22, and a = 0.941565(12) nm, c = 5.22254(8) nm. A 2D 10-&10-rings micropore structure is incorporated in the layered framework consisting of AlO₄, AlO₆, and PO₄ polyhedra. The structure of AlPO-NS was changed into a disordered structure derived from stacking faults by the calcination above 573 K under the atmosphere. This structural change is due to shrinkage of the interlayer space and (partially) bridging adjacent aluminophosphate layers by dehydration-condensation of facing –OH groups. The calcined AlPO-NS showed nitrogen adsorption ability with a nearly type-I adsorption isotherm. A specific surface area (S_BET) and micropore volume (V_micro) were 300 m² g⁻¹ and 0.11 mL g⁻¹, respectively. As-synthesized AlPO-NS contained H⁺ ions for charge compensation and exhibited ion exchange abilities for Na⁺ and K⁺ ions when immersed in NaCl and KCl aqueous solutions, respectively. From the above, it was found that AlPO-NS and its calcined form have micropores and physicochemical properties similar to zeolites.

结合 3D-ED、粉末 X 射线衍射和固态，确定了新型磷酸铝 AlPO-NS 的晶体结构，其晶体形态为堆叠六方板微晶（厚度 30-50 nm）核磁共振实验。我们之前报道过，AlPO-NS可以_{通过AlPO 4从典型的磷酸铝AlPO 4} -5 (Al ₂ O ₃ : P ₂ O ₃ : 三乙胺: H ₂ O = 1.0 : 1.0 : 3.0 : 250)的合成溶液中获得-5 通过延长水热反应时间（T. Kodaira et al. Microporous and Mesoporous Materials 162 , 32–35 (2012).）。3D-ED/microED 分析成功揭示了 AlPO-NS 在六方晶系的晶胞中由两层组成。空间群和晶格常数为P 6 ₃ 22， a  ＝0.941565(12)nm， c  ＝5.22254(8)nm。_{在由AlO 4}、AlO ₆和PO ₄多面体组成的层状框架中引入了2D 10-&10-环微孔结构。通过在大气中573 K以上的煅烧，AlPO-NS的结构转变为源自堆垛层错的无序结构。这种结构变化是由于层间空间的收缩和通过面对的-OH基团的脱水缩合（部分）桥接相邻的铝磷酸盐层造成的。煅烧后的AlPO-NS表现出氮吸附能力，具有接近I型吸​​附等温线。比表面积( S _BET )和微孔容积( V _micro )分别为300m ²  g ^-1和0.11mL g ^-1。合成的 AlPO-NS 含有用于电荷补偿的^{H +离子，并且}当分别浸入 NaCl 和 KCl 水溶液中时，表现出与 Na ⁺和 K ^{+离子的离子交换能力。}由上可知，AlPO-NS及其煅烧体具有与沸石相似的微孔和物理化学性质。
