摘要:

采用共模板法以二乙胺和1,2-丙二胺为模板剂, 合成了过渡金属取代的二维层状磷酸铝化合物[C4H11N]0.77[C4H12N]0.23[C3H12N2]2[Co0.23Al5.77P8O32][H3O]2(1). 通过X射线衍射(XRD)、 热重分析(TG)、 元素分析(ICP-AES及CHN)、 固体紫外-可见分析(Solid-UV-Vis)及扫描电子显微镜(SEM)等对化合物1进行了表征. 该化合物属三斜晶系, P1-空间群, 晶胞参数a=0.95029(19) nm, b=1.2689(3) nm, c=1.2987(3) nm, α=118.70(3)°, β=97.64(3)°, γ=99.72(3)°, V=1.3117(5) nm3, Z=1. 其无机骨架由铝(或钴)氧四面体(AlO4或CoO4)和磷氧四面体PO3(=O)严格交替连接形成4,6,12-网层结构, 无机层沿[001]方向堆砌成一维十二元环孔道. Co无序取代Al的位置, 其Co/Al摩尔比约为1∶25.1. 运用分子动力学模拟的方法, 通过计算有机模板剂和无机骨架的相互作用, 讨论了2种有机胺分子的共模板作用.

Abstract:

In the presence of diethylamine and 1,2-diaminopropane, a new microporous cobalt-containing aluminophosphate compound [C4H11N]0.77[C4H12N]0.23[C3H12N2]2[H3O]2[Co0.23Al5.77P8O32](1) was synthesized. The structure of compound 1 was determined by single-crystal X-ray diffraction(XRD) analysis and further characterized by X-ray powder diffraction, thermogravimetric analysis(TG/DTA), inductively coupled atomic emission spectrometry(ICP-AES), CHN, Solid-UV-Vis spectrometry and scanning electron microscopy(SEM). It crystallizes in the triclinic system, space group P1-, with a=0.95029(19) nm, b=1.2689(3) nm, c=1.2987(3) nm, α=118.70(3)°, β=97.64(3)°, γ=99.72(3)°, V=1.3117(5) nm3, Z=1. The structure are built up from strict alternation of CoO4/AlO4 and PO3(=O) units. It contains 12-membered ring channel along [001] direction. The molar ratio of Co to Al is 1∶25.1. We also calculated the interaction energy and studied the co-template role of those two amines by the molecular dynamics method.
