| 摘 要： | 应用一锅法合成了Keggin结构ⅡB族元素取代的钨硼杂多酸盐K7BW11 O39 M( H2O)](M=Zn,Cd),用元素分析、傅里叶变换红外光谱、紫外光谱、X射线粉末衍射等手段对其结构进行了表征.以生物偶氮染料甲基红模拟废水,考察了紫外光照射下K7 BW11 O39 M(H2 O)]的光催化性能.结果表明,对pH 2的25 μmol· L-1甲基红水溶液,K7 BW11 O99 M(H2 O)]投加量为20 mg·L-1,光照60 min时,甲基红的降解率可达95%以上.

| Abstract: | The Keggin II B element-monosubstitiuted heteropoly compounds with the stoichiometry of K7 BW11 O39 M(H2O)] (M = Zn, Cd) were prepared by one-pot method and characterizated via elemental analyses, FTIR, UV and XRD. The photocatalytic activity of K7 BW11O39M(H2O)] was tested vis degradation of the model molecule, methyl red (MR). After 60 min irradiation in the presence of K7 BW11O39M(H2O)] (20 mg x L(-1)), the degradation rate of an aqueous MR (25 micromol X L(-1), pH 2) got to 95%. |
