摘要
以K7HNb6O19·13H2O,Na2SeO3,NaH2PO4·2H2O和YCl3·6H2O等为原料,利用常规水溶液法合成了一例新型的基于{P2Se2Nb6(O2)6O22}单元的杂多过氧铌簇稀土衍生物Cs2K2H{6[Y(H2O)5][P2Se2Nb6(O2)6O22]}2·12H2O(1),并通过红外光谱、元素分析、热重分析和X射线单晶衍射等分析手段对其进行了表征.化合物1含有一个V型的多酸阴离子簇{[Y(H2O)5][P2Se2Nb6(O2)6O22]}210-,该阴离子依次连接形成一维链状结构.此外,对该化合物的催化光解水产氢性能进行了研究.
Abstract
A new rare earth derivative of hetero peroxopolyoxoniobate based on{P2Se2Nb6(O2)6O22}unit,Cs2K2H6{[Y(H2O)5][P2Se2Nb6(O2)6O22]}2·12H2O(1),has been successfully synthesized by the reaction of K7HNb6O19·13H2O,Na2SeO3,NaH2PO4·2H2O and YCl3·6H2O in a conventional aqueous solution method.It was structurally characterized by IR spectrum,elemental analysis,TG analysis and X-ray single crystal diffraction,etc.The results show that compound 1 contains a V-shaped polyoxoanion{[Y(H2O)5][P2Se2Nb6(O2)6O22]}210-,which is connected in turn to form a one-dimensional chain structure.In addition,the photocatalytic H2 evolution activity of compound 1 was studied.
