| 摘 要： | A polyoxometalate K_(13)Gd(GeW_(11)O_(39))_2]·34 H_2 O was synthesized and characterized by elemental analysis,IR spectroscopy, UV spectra, XRD and thermal gravimetric analysis. X-ray single-crystal structural analysis indicates that the title compound crystallizes in the triclinic crystal system. The heteropolyanion of Gd(GeW_(11)O_(39))_2]~(13) consists of two GeW_(11)O_(39)]~(8-) vacant Keggin moieties linked via Gd~(3+). Photocatalytic performance of K_(13)Gd(GeW_(11)O_(39))_2]·34 H_2 O in photodegradation of X-3 B was also studied.When the reaction time is 180 min, the decoloring rate reaches 71.19%. With the decrease of pH, the decolorization rate increases gradually.

| Abstract: | A polyoxometalate K13Gd(GeW11O39)2]·34H2O was synthesized and characterized by elemental analysis, IR spectroscopy, UV spectra, XRD and thermal gravimetric analysis. X-ray single-crystal structural analysis indicates that the title compound crystallizes in the triclinic crystal system. The heteropolyanion of Gd(GeW11O39)2]13? consists of two GeW11O39]8– vacant Keggin moieties linked via Gd3+. Photocatalytic performance of K13Gd(GeW11O39)2]·34H2O in photodegradation of X-3B was also studied. When the reaction time is 180 min, the decoloring rate reaches 71.19%. With the decrease of pH, the decolorization rate increases gradually. |
