| 摘 要： | 在常规条件下合成4个新型的稀土-Anderson型多金属氧酸盐拓展结构化合物(C5H9NO2)2Ln(H2O)7AlMo6H6O24].11H2O(Ln=La(1),Ce(2),Pr(3),Gd(4);C5H9NO2=脯氨酸),并通过元素分析、红外光谱、紫外可见光谱、热重分析和X射线单晶衍射等方法对化合物晶体结构进行了表征。结构分析表明:以上4个化合物是同构的,均结晶在单斜C2/c空间群。在这些结构中,Al(OH)6Mo6O18]3-首先通过稀土离子连接形成一维链,相邻的链再进一步通过脯氨酸和结晶水分子的氢键作用形成三维超分子结构化合物。我们以化合物1为代表研究了这类化合物的光催化性能,在紫外光照射下表现出很好的降解RhB(罗丹明B)的光催化性质。

| Abstract: | Four new compounds based on Anderson-type polyoxometalates (C5H9NO2)2Ln(H2O)7AlMo6H6O24]·11H2O Ln=La (1), Ce (2), Pr (3), Gd (4); Proline=C5H9NO2], have been synthesized and characterized by elemental analysis, IR spectroscopy, UV-Vis spectroscopy, TG analysis and single-crystal X-ray diffraction analysis. All the compounds are isostructures, and crystallize in the space group C2/c. In the structure, the B-type Anderson polyoxoanions Al(OH)6Mo6O18]3- are linked by rare-earth cations to form a one-dimensional chain. And then the adjacent chains are further connected by proline and lattice water molecules to a 3D supramolecular structure. The photocatalyst property of compound 1 has been studied, which shows an excellent photocatalyst effect by photodegradation of RhB dye under UV- irradiation.
