| 摘 要： | 用吡啶代替四乙二醇作为溶剂, 在Al2O3-H3PO4-C6H11NH2-Py体系下合成出层状阴离子骨架磷酸铝［Al2P3O12H］2-·2［C6H11NH+3］(UT-4)的纯晶相, 采用一维27Al， 31P MAS NMR , 1H→31P CP(Cross Polarization)以及二维27Al- 31P HETCOR(Heteronuclear Correlation)高分辨固体核磁共振技术对其骨架结构进行了表征. 采用两种方法对 27Al信号进行了归属, 并通过分析27Al-31P HETCOR谱对31P 信号进行了归属.

| Abstract: | Pure UT-4 crystalline phase was synthesized by using pyridine as the solvent instead of TEG in the system of Al2O3-H3PO4-C6H11NH2-Py. 27Al MAS NMR, 31P MAS NMR, 1H→1P cross-polarization(CP) and 27Al-31P heteronuclear correlation(HETCOR) experiments were employed to investigate the framework of UT-4, a two-dimensional layer aluminophosphate, which was first synthesized in the system of TEG, coexisting with UT-5. In the assignment of two four coordinated Al atoms, two methods were used. The assignment of 31P signals is based on the 27Al-31P HETCOR spectrum. |
