采用一锅法制备了化学计量为K-7[BW11O39M(H2O)] (M=Zn, Cd)的Keggin II B元素单取代杂多化合物，并通过元素分析、FTIR、UV和XRD进行了表征。 K-7[BW11O39M(H2O)] 的光催化活性通过模型分子甲基红 (MR) 的降解进行了测试。在 K-7[BW11O39M(H2O)] (20 mg.L-1) 存在下照射 60 分钟后，水性 MR (25 μmol.L-1, pH 2) 的降解率达到 95%。
The Keggin II B element-monosubstitiuted heteropoly compounds with the stoichiometry of K-7[BW11O39M(H2O)] (M=Zn, Cd) were prepared by one-pot method and characterizated via elemental analyses, FTIR, UV and XRD. The photocatalytic activity of K-7[BW11O39M(H2O)] was tested vis degradation of the model molecule, methyl red (MR). After 60 min irradiation in the presence of K-7[BW11O39M(H2O)] (20 mg . L-1), the degradation rate of an aqueous MR (25 mu mol . L-1, pH 2) got to 95%.
