| Abstract: | A new polyoxometalate compound, Ag4H3PTi2W10O40·16H2O(1), was synthesized with Keggin-type potassium dititanodecatungstophosphate and silver acetate as raw materials. The produet was characterized by thermogravimetric analysis(TGA), infrared spectrum(IR), and solid diffuse reflectance spectrum(DRS). Single crystal X-ray diffraction shows that {AgO6} units in compound 1 bridge H3PTi2W10O40]4-, leading to the formation of a two-dimensional layer structure parallel to ab-plane. And the two-dimensional layer can be further extended to three-dimensional network structure. Besides, DRS analysis indicates that compound 1 can absorb visible light and may be an excellent photocatalytic material. |
