摘　　要：用溶剂法合成了Waugh结构的杂钼多酸晶体(NH_4)_6[MnMo_9O_(32)]·8H_2O,用X-射线单晶衍射仪测定其结构,并对其进行了X-射线粉末衍射、红外光谱、固体紫外漫反射、热重等表征.并研究了化合物对亚甲基蓝染料的光催化降解性能.试验结果表明:在自然光下该化合物对亚甲基蓝光催化120 min,其降解率可以达到86.76%.A Waugh-type polyoxomolybdate was synthesized by solvent method. The crystal structure was determined by X-ray single crystal diffraction. The compound was structurally characterized by X-ray powder diffraction, UV-vis DRS, IR and TG. The photo-catalytic degradation of Methylene blue dye were carried out using the compound as catalyst. It was found that the photoeatalytic degradation rate of compound toward Methylene blue dye was able to reach 86.76% under normal light after 120 min.
