Abstract
A polyoxometalate-templated metallacycle compound, [Ag6trz6][H3PMo12O40]2·6H2O (trz = 1,2,3-triazole), has been isolated and structurally characterized. The compound represents the first example of a trigonal antiprism based metal-organic framework (MOFs) with complicated Zr6Br12 type topology, in which the trigonal antiprisms as building blocks are constructed by the Ag6trz6 space polygons and the bifunctional POMs (both as template and building block). In addition, to improve the photocatalytic activity of polyoxometalate-templated metallacycle compound, polypyrrole was loaded on its surface through a chemical oxidation polymerization process in situ. Finally, the photocatalytic activity of [Ag6trz6][H3PMo12O40]2 and PPy@[Ag6trz6][H3PMo12O40]2 under visible light was explored, and the results demonstrate that the PPy loading on the surface of POMs-based hybrid compound is feasible to improve their photocatalytic performance.
